muLtiLayer/3D microWaVe anD miLLimeterWaVe mcm/Sop: recentS aDVanceS anD cHaLLengeSHalf Day PM | Room 203

Overview: Due to several advantages of higher frequency, microwave and millimetre-Wave (MMW) have found an ever-in-creasing interest for commercial as well as military applications. Monolithic Integrated Circuit (MMIC/RFIC) technologies offer a means for fabricating large quantities of highly reproducible, low-cost mm-wave circuits. But, at high frequency the module/circuit assembly techniques are more complex and costlier. The multilaye/3D integration technologies, such as Multi-Chip-Module (MCM) or system-in/on-package (SoP) is widely favoured as an excellent technique for realizing compact system with ever-greater product functionality and repeatability at a low cost. The past decade has seen enormous advancement in these technologies, yet many challenges are still to address. This workshop will attribute a wide range of presentations and will provide a complete outline and understanding on multilayer advanced MCM/SoP technologies (including LTCC, LCP, Photoimageable thick-film and BCB) and their challenges, and will aware the participants on recent and important progresses including, co-designing MMICs with package (SOC with SOP) and integrating mix technologies for emerging MCM/SoP applications. The speakers are the experts and are all leading contributors in both industrial and academic sectors.

Overview: In MIMO systems, spatial correlation, which is a function of both antenna and propagation characteristics, plays a key role. Indeed, the level of correlation cannot be determined based on propagation characteristics without knowing the characteristics of the antenna. Similarly, the level of correlation cannot be determined based on the antenna characteristics without knowing the propagation characteristics. Therefore, it is necessary to include both antenna and propagation characteristics at the same time when testing multi-antenna terminals. In order to understand the end-to-end reception performance of a multiple antenna device, Over-the-Air (OTA) testing is needed. Due to the complexity of multiple antenna set-upsetups, a flexible and fast accurate testing solution becomes a major asset in the antenna design cycle and final product verification (and consequently, Time To Market). To date, three fundamentally different approaches are being studied by the wireless industry through 3GPP (3rd Generation Partnership Project) [1] , COST2100 (European Cooperation in Science and Technology) [2], and CTIA (International Association for the Wireless Telecommu-nication Industry). The first one is the Anechoic Chamber Based that which simulates a complex multipath environment at the device location of the device in a repeatable way by using radio channel emulators connected to a circular array of probes [3] and, [4]. The 2other 2 one are the reverberation chamber and the multistage methods. This aim of this workshop is to demonstrate the relevant features and details of the anechoic chamber based method and highlight the advantages wrt to other approaches.

“redefininG The leadinG edGe: iT’s a maTTer of PersPeCTive”Paul Colestock, Director of Market Strategy, GLOBALFOUNDRIES

Abstract: In today’s semiconductor industry, the race to each new process generation and technology innovation gets most of the headlines. But as the arms race to build 28, 20 and 14 nanometer chips wages on, mainly to the benefit of high profile digital centric applications, we tend to forget the less glamorous but no less critical innovation that may be required in more mainstream and mature technologies. Analog, Mixed Signal, RF and MEMs ICs specifically represent a high growth market opportunity that is critical to the notion of ubiquitous computing and the Internet of Everything. This talk will look at a new wave of technical challenges outside of the leading edge digital domains, challenges that require the brightest minds working together and higher levels of collaboration – early, often and deep.

We’ll further examine the evolution and future of the foundry model, the technical and business drivers reshaping the landscape, and how fabless and IDM companies must change their perspective on what has worked in the past, regardless of how you define ‘leading edge.”

Biography : Paul Colestock has served as the Director of Market Strategy at GLOBALFOUNDRIES Inc. since July of 2012. Mr. Cole-stock’s responsibility is to effectively strategize, plan, build, deliver and monetize vertical market centric products, IP and tech-nologies.

TU3A-1 1335 – 1355A Design of Integrated Ultra-wideband/Narrow Band Rectangular Dielectric Resonator AntennaY . F . Wang1,2, T . A . Denidni2, Q . S . Zeng3, G . Wei1, 1Northwestern Polytechnic University, Xi’an, China, 2University of Quebec, Montreal, Canada, 3Communications Research Centre Canada, Ottawa, CanadaAn ultra-wideband (UWB) rectangular dielectric resonator antenna (DRA) integrated with a narrow-band (NB) DRA is presented . The proposed antenna consists of a UWB rectangular DRA excited by a bevel-shaped patch and a NB DRA excited by a strip . The simulated results demonstrate that the UWB antenna provides a 2:1 voltage standing wave ratio (VSWR) bandwidth for 2 .5 – 12 GHz, integrated with a NB antenna . Moreover, the two ports have the same polarization, and two symmetrical short circuited strips are used to improve the isolation between the two ports . This can be a suitable candidate for applications in cognitive radio, where the UWB antenna can be used for spectrum sensing and the NB antenna for communication operation .

TU3A-2 1355 – 1415A novel circular polarized diamond ring-slot antenna design based on SIW structureF . Fan, W . Wang, Z . Yan, Xidian University, Xi’an, ChinaA single-layer right-handed circularly polarized (RHCP) substrate integrated waveguide (SIW) diamond ring-slot antenna at X-band is proposed in this paper . By a shorted diamond ring-slot in the top wall of SIW and a shorting via between the top patch and the bottom ground plane, the RHCP wave and wideband impedance bandwidth are obtained at the same time . The measured impedance bandwidth and axial ratio (AR) bandwidth are 14 .5% (10 .03-11 .6GHz) and 3 .4% (10 .16-10 .51GHz), respectively . The antenna has good radiation pattern and high gain than other similar SIW antennas .

TU3A-3 1415 – 1435A Thin and Compact High Gain Planar Antenna Integrated with a CMRC Compact FilterS . Yeung1,1, A . García-Lampérez2,2, T . K . Sarkar1,1, M . Salazar-Palma2,2, 1Syracuse University, Syracuse, United States, 2Universidad Carlos III de Madrid, Leganes, Madrid, SpainThis paper presents a thin and compact high gain planar antenna integrated with a CMRC compact filter . The high gain antenna is a 4 element broadside microstrip array fed by parasitic coupling . The antenna is developed on a thin substrate of 0 .762 mm thick . The broadside gain is 11 .37 dBi at 5 .5 GHz . The CMRC filter has filtered out the higher order modes of the micostrip antenna till 16 GHz . The sizes of the antenna array with and without the CMRC filter are exactly the same . Therefore, the design presented is a promising technique in designing a thin and compact high gain planar antenna with low-noise received .

TU3A-4 1435 – 1455Design of a Handheld UHF RFID Quasi Yagi microstrip antenna using Meander line bridge Frequen-cy selective surfaceS . G . Kim, J . J . Song, T . W . Kim, Pyongyang University of Science and Technology, Pyongyang, Democratic People’s Republic of KoreaThis paper presents a quasi yagi microstrip antenna which is backed by meander line bridge Frequency selective surface (MBFSS) for a handheld UHF RFID reader . Long read range handheld reader antennas have been usually packaged outside of the reader units in most cases due to the mutual coupling and environment effect . In the proposed antenna, we reduce such effects by placing MBFSS under the quasi yagi antenna, so that the antenna is packaged inside the reader module with long read range . The proposed antenna has been simulated and measured using some measurement setups . 4 .8dBi gain, 12 .9dB front –to –back ratio and VSWR 1 .5 have been obtained in 50MHz band centered around 917MHz . Return loss at the center frequency is -31 .2dB .

Sun3, 1University of Electronic Science and Technology of China, Chengdu, China, 2Comba Telecom Systems Holdings Limited, Guangzhou, China, 3The University of Hong Kong, Hongkong, Hong KongA miniaturized antenna with circular polarization and directional pattern is presented in this paper . The con-ventional ground plane is replaced by a rectangular ring reflector to form the directional pattern . Since the side length of the ring reflector is around quarter-wavelength, the total size of the proposed antenna is reduced dramatically, which is about lambdag/2 by lambdag/2 in the horizontal plane . In addition, the performance of the proposed antenna is still comparable with the convetional microstrip antenna . The simulated gain is 6 .1 dB at the 1 .575 GHz, while the back radiation is only -11 .6 dB . To verify the proposed design, a protype is fabricated and measured . Good agreement is observed between the measured and simulated results .

Yu, ETRI, Daejeon, Republic of KoreaAbstract — A 77GHz CMOS 4-channels receiver, transmitter with 3-outputs and array antenna architecture is proposed for low cost/small size automotive radar system, and implemented by using 65nm CMOS technology and LTCC substrate . Measured performance of CMOS transceiver, which included useful functions such as dual operation of long/short range detection, I/Q signal process and gain attenuation when near target detection, shows comparable performances to that of commercial SiGe radar chips . Especially, the transmitter consumes one third lower power compared to SiGe chips . These results confirm that it may be a promising candidate for low cost and small size car radar system .

TU3C-2 1400 – 1425Ceramic Based Novel Multilayer and Miniaturized RF/Millimeter-Wave Components and Highly Integrated Mm-Wave Modules K . K . Samanta1,2, 1Milmega Ltd, Ryde, United Kingdom, 2University of Leeds, Leeds, United KingdomThis paper describes the realization of novel multilayer miniaturized and high performance passive compo-nents, covering a wide frequency range (RF to millimeter-wave), and a highly compact millimeter-wave sub-systems at a low cost using advanced multilayer ceramic based photoimageable thick film technology . The multilayer miniaturized passive components have been designed using meander-line and lumped-distributed approach, and characterized covering IF (2GHz) as well as RF ( 80 GHz) frequencies for a complete system . At the same time compact and high-Q multilayer lumped components have been designed and modeled up to mmW frequency with excellent performance . Lumped element filters have remarkably low pass band loss with high stop band attenuation and miniaturization . These performances are better than most of the reported results from conventional multichip module (MCM) technologies . Further, using a new integration technique, where IC mounting cavities are formed from trench-vias and have precise dimensional control, a mmW modules are realized onto a single substrate integrating MMICs with RF (V-band) SIW components and embedded lumped element (IF) low-pass filter and other passives in bias network with high performance and compactness .

In addition, a V-band LNA using the proposed Pi-type ESD block is demonstrated in 65-nm CMOS . A series ESD inductor together with two shunt ESD diodes and an bonding (probing) pad form a Pi-type network, acting like an ideal wideband 50-ohm transmission line with a loss of only 0 .6 dB at 60 GHz . Under a power consumption of 27 mW, the ESD-protected LNA presents a 4 .1-dB NF and 18 .5-dB power gain at 60 GHz, respectively with a 3-dB bandwidth up to 7 .7 GHz . The measured results also demonstrate a 2 .5-kV Human-Body-Model (HBM) ESD protection . This LNA shows excellent FoMs compared with recently published results in a similar frequency range .

TU3C-4 1450 – 1515Pulse-Modulated Polar Transmitters for Spectrum-Efficient Wireless ApplicationsY . E . Chen1, H . Yang1, J . Chen2, 1National Taiwan University, Taipei, Taiwan, 2National Taiwan University, Taipei, TaiwanThe pulse-modulated polar transmitters have been developed to answer the call for the need of linear and efficient power amplification for wireless applications . The envelope of the modulated RF signal is converted into the pulse train by means of pulse width modulation or delta-sigma modulation . The power amplification of the pulse train can be performed by the highly efficient power amplifiers without the constraint of linearity . The modulated RF signal can be restored by low-pass or band-pass filtering of the amplified pulse train . With both high linearity and high efficiency, the pulse-modulated polar transmitter is an excellent candidate for spectrum efficient wireless applications .

Chair: Richard V . Snyder, RS MicrowaveCo-Chair: Ke Wu, Montreal Polytechnique

In this session, the audience will view some imporvements in state of the art synthesis and implementation of microwave filters, with applications to bandpass, bandstop and tunable structures .

TU3D-1 1335 – 1355A Hybrid Method for Flat-Passband Filter with Nonuniform Q Resonators and PredistortionL . Qiu1, L . Wu1, W . Yin2,1, 1Shanghai Jiao Tong University, Shanghai, China, 2Zhejiang University, Hangzhou, ChinaA new synthesis method is proposed for the design of high-performance parallel connected lossy filters . Com-pared with the nonuniform Q method, where the Q distribution is determined by the sensitivities of a preset coupling matrix, our method can provide a flat passband with flexible combination of nonuniform Q resonators by utilizing the predistortion technique with an adaptive offset . Two generalized Chebyshev filters with dif-ferent specific Q-factors are designed with the negative and positive distortion offsets . The proposed hybrid method has been validated by the perfect passband flatness achieved with both of them .

TU3D-2 1355 – 1415High Selectivity Wideband Differential Bandpass Filter with Wideband Common Mode Suppres-sion Using Marchand BalunW . Feng1, W . Che1, Q . Xue2, 1Nanjing University of Science and Technology, Nanjing, China, 2City University of Hong Kong, Hong Kong, ChinaA novel compact high selectivity wideband differential bandpass filter with wideband common mode sup-pression using Marchand balun is presented in this paper . Open/shorted coupled lines and stubs are used to improve the selectivity for the differential mode and common mode suppression . The demonstrated filter with a compact size of 24 mm × 12 mm exhibits a fractional bandwidth of 53% centered at 3 .0 GHz and 13 dB common-mode suppression from 0 to 9 GHz (3f0) .

TU3D-3 1415 – 1435A New Balanced-to-Single-Ended (BTSE) Power DividerL . Wu1,2, Y . Guo2,3, L . Qiu1, J . Mao1, 1Shanghai Jiao Tong University, Shanghai, China, 2National University of Singapore, Singapore, Singapore, 3National University of Singapore (Suzhou) Research Institute, Suzhou, ChinaA balanced-to-single-ended (BTSE) power divider is proposed in this paper . Its input is a differential pair while both the outputs are single-ended ports . It can replace the cascade of a balun and a conventional power divider . The characteristics requirements of a two-way BTSE power divider with equal power division are first derived, and then a prototype is designed for 2 .0 GHz . In order to construct the component compactly, a short-ended four-wire coupled line and T-shaped sections are utilized to realize a -90° transmission line and a phase inverter, respectively . The developed prototype occupies an area of 0 .077 λg2, where λg is the guided wavelength of central frequency . It provides all the desired performances within the operating bandwidth of 25%, with low insertion loss and good balance also achieved .

TU3D-4 1435 – 1455A 2.285 - 3.195 GHz Electrical Tunable Bandstop Filter with Constant Absolute Bandwidth Q . Xiang, Q . Feng, X . Huang, D . Jia, Southwest Jiaotong University, Chengdu, ChinaIn this paper, a tunable bandstop filter with constant absolute bandwidth is proposed based on electric coupling compensation of tunable capacitor network . The equivalent circuit model of the tunable capacitor network is presented to study the tunable mechanism . The electric coupling factor of the tunable capacitor network in-creases while the tunable capacitor increasing . This mechanism can be used to compensate the bandwidth of the tunable bandstop filter . In our work semiconductor varactor diode loaded microstrip LC resonator is adopted to design the tunable filter . Each resonator requires only one varactor diode for both central frequency and resonator coupling coefficient control . The S-parameters and group delays of the tunable bandstop filter are presented . The measurement shows that the -30 dB absolute bandwidth varies from 371 MHz to 305 MHz while the central frequency of the stopband varying from 3 .195 GHz to 2 .285 GHz .

TU3D-5 1455 – 1515Quasi-Elliiptic Compact High-Power Notch Filters With Selectivity Both Below and Above the Notched PassbandR . V . Snyder, RS Microwave, Butler, United StatesA quasi-elliptic notch filter response is defined as one in which the ultimate stopband depth is sacrificed in favor of a faster transition from the passband to a specified minimum equi-ripple stopband attenuation level (i .e . steeper attenuation slope) with no increase in filter order (as compared to a Chebychev or similar transfer function design) . Such notch filter responses can be achieved if the topology synthesized includes arbitrary frequency variant impedances and line lengths in the main series line of filters, otherwise similar to those in the original 1992 design, as was shown in 1999 (both by this author) . The networks of the 1999 design exhibit lowpass characteristics above the notched passband . In this paper, we substitute high pass sections for some of the lowpass series inverter sections of the 1999 design, thereby achieving selectivity both above and below the notched passband . This removes the frequent requirement to “window” the notched passband (add a bandpass filter) for harmonic and subharmonic suppression . The resulting filters exhibit lower loss than earlier “win-dowed” notch assemblies, provide selectivity above and below the system passband, without sacrificing notch characteristics required within the system passband .

Yang, Southeast University, Nan Jing, ChinaMultiple-Input-Multiple-Output (MIMO) technology plays an important role in the fourth generation and future wireless communication systems to meet the exploding capacity requirements . In conventional MIMO approaches, antenna elements are placed far away from each other to eliminate the correlation and make use of the spatial multiplexing . However, this advantage offered by the MIMO comes at the price of losing the beam-forming ability in the smart antenna system . We propose a new technique for MIMO communication with active phased antenna array in each transmitter/receiver which we call hybrid phased array MIMO . Coherent process-ing gain can be achieved by designing a weight vector for each subarray to form a beam towards a certain direction in space . Moreover, the subarrays are treated jointly to form a MIMO system . A four-input-four-output hybrid phased array MIMO system for TD-LTE base station is designed and implemented . The measured results validate the effectiveness of the proposed system .

The return loss of the proposed antenna is higher than that desired for one-port antenna application at the desired dual-band frequencies . The antenna is fabri-cated on one side of a Neltec substrate (εr=3 .2 and thickness = 0 .762 mm) and the microstrip feeding line is fabricated on the opposite side of the board . The antenna was designed to operate at WLAN bands centered at 2 .4 and 5 .2 GHz . The simulated and measured results show fairly good agreement . The measured return losses were found 10 dB at 2 .4 GHz and 14 .5 dB at 5 .2 GHz while simulated return losses were 8 .57 dB at 2 .4 GHz and 15 .2 dB at 5 .2 GHz . The radiation pattern is approximately omnidirectional at both frequencies in H-plane .

Zhao2,2, 1University of Electronic Science and Technology of China, Chengdu, China, 2Institute of High Performance Computing, Singapore, SingaporeIn this paper, we address the optimization of a two-way Multiple-Input-Multiple-Output (MIMO) Ampli-fy-and-Forward (AF) relay network . We consider a multiple access broadcast scheme which finishes commu-nication in two time slots . In order to optimally choose the beamforming coefficients of relays, we devise the following criteria: the beamforming coefficient matrices are optimized aiming to minimize the total relay trans-mission power subject to output Signal-to-Noise-Ratio (SNR) constraint at each transceiver . To design the MIMO equalizer, we impose the Zero-Forcing (ZF) constraint . Since the original optimization problems generated from the criteria are intractable, compromise is essential . So we consider local optimum the problems . Through relax-ation, we find that the relaxed optimization problems can be formulated as the Second-Order-Cone-Program-ming (SOCP) problems which can be solved efficiently using the existing toolboxes . The validity of the proposed algorithm is verified by computer simulations .

Numerical results show that the derived SBP yields almost the same performance as the BP decoders in the literature, while the computational complexity is reduced significantly, which make our SBP more suitable for practical application as compared to the existing BP decoders .

Simu-lation results show that NSO-CC effectively solves the problem of nodes non-uniform sleeping, improves the network coverage quality and prolongs the network lifetime .

Li, Southeast University, Nanjing, ChinaThis paper proposes a novel synchronization algorithm for multiuser digital impulse radio (IR) ultra-wideband (UWB) system . The proposed algorithm is based on pseudo-noise (PN) training sequence, and different users employ different PN sequences .

The proposed scheme includes acquisition and timing (fine synchroni-zation) algorithms . Acquisition and coarse channel estimation are firstly gotten . After that, timing and channel estimation can be derived at the same time naturally through energy searching . In multipath channel, no in-terference among the pulses inner preamble is guaranteed and inter frame interference (IFI) inner one symbol during payload transmitting is allowed .

WE1C-2 0900 – 0920DOA Estimation Accuracy Improvement for Circular Array Interferometer with Analog Phase Detector and Its FPGA ImplementationY . Pan, N . Tai, J . Huang, N . Yuan, National University of Defense Technology, Changsha, China Circular array interferometer with analog phase detector requires higher signal to noise ratio than the digital phase detection structure, which leads to lower accuracy of direction-of-arrival (DOA) estimation . To overcome this, we proposed two kinds of methods which can work together . They are the modified phase accumulation method (MPAM) and the optimal baseline pair method (OBPM) . Modified phase accumulation method solves the problem caused by phase jump near ±πin analog phase detection structure in conventional phase accu-mulation method (CPAM) . Taking the azimuth corresponding to one certain baseline pair as reference, OBPM outputs the azimuth and elevation corresponding to the highest accurate baseline pair .

The SNR-maximized is implemented at the receiver based on selecting the relay to cooperate or not . The receiver can always find the optimal selected relay by exhaustive search where the number of relays is only two . It is shown in this work that the proposed scheme obtains full diversity order and provides an additional array gain compared to conventional Al-DSTC . The pro-posed scheme has a lower bit error rate if compared to the beamforming when the transmit power is high . Our results show that the proposed scheme is more power efficient than the conventional Al-DSTC and cooperative beamforming . Also, the proposed scheme increase life time of the relay since 50% of the time the relay is off .

Pan, China Mobile Research Institute, Beijing, ChinaEnergy efficiency (EE) has been recognized as another important metric as well as spectral efficiency (SE) . This paper investigates the fundamental properties of the EE-SE relationship for point-to-point MIMO transmission link . Reducing circuit power is helpful to improve EE in the low SE region while introducing more antennas benefits the EE in the high SE region . We also study the properties of EE-optimal points . It is found that reducing circuit power brings exponential EE increasing with linear SE loss at the EE-optimal points . More multiplexing gain will alleviate the speed of EE reduction with the increase of SE . More diversity gain brings a fixed EE gain . Above conclusion is also suitable to MIMO systems with active antennas . With the given number of antennas, there is an optimal number of transceivers to maximize the EE for each SE value .

WE2A-1 1040 – 11003-D Ambiguity Analysis Method Of Arbitrary Antenna Array For Direction FindingW . Kuang, X . Zhang, X . Jiao, C . Chen, Nokia, Beijing, ChinaIn this paper we propose an approach to 3-D ambiguity (type I ambiguity [l]) analysis of arbitrary antenna arrays . Ambiguity characterization is very important in designing antenna array for direction finding in mobile communications/indoor positioning/radar, which greatly influences practical capability of Direction of Arrival (DOA) estimation . Conventional 2-D ambiguity analysis loses most of ambiguity information in 3-D space and cannot indicate ambiguity from 3-D space out of the selected 2-D plane; Cramér–Rao bound (CRB) analysis outputs unidentified pattern when real measured data exhibits less regular behavior than ideal data, moreover it only provides variance low bound instead of exact value or upper bound . We defined and proposed the 3-D ambiguity analysis with full 3-D ambiguity information of antenna array, and shows (by real measured data) that proposed method is a plain and utility tool for ambiguity characterization suitable for practically designing arbitrary antenna arrays .

The method reconstructs the excitation source of all elements utilizing the sparsity of the excitation vector, which improves the accuracy of the source reconstruction . Meanwhile, the sparse excitation source reconstruction provides straightforward information on the failing elements . However, same as other diagnosis methods, the diagnosis reliability of sparse excitation source reconstruction depends on the position of near field observations . In order to facilitate the positioning of near field observations, this work presents numerical study on the diagnosis relia-bility against the position of near field observations . Based on numerical experiments, guidelines on positioning near field observations are presented .

The model is based on the multiple-input-multiple-output (MIMO) measurements at 2 .6 GHz . The model is divided into two scenarios, i .e ., line-of-sight (LOS) and non-LOS (NLOS) . In the case of LOS, the path loss exponent n decreases slightly with the increasing of frequency and is fitted by the frequency using power function . In the NLOS one, the path loss on different steps in the same part of the stairwell is similar, while it has an obvious increasing when the stair-well makes a turn .

Li, Zhengzhou, ChinaMultiple-channel cooperative spectrum sensing in cognitive radio networks (CRN) based on cognitive radios with single antenna had been widely researched . However, it should be studied more to get the optimal an-tenna assignment in multiple-channel coordinated spectrum sensing for multiple antennae based cognitive radio networks when multi-antenna cognitive radios can flexibly select their antennae to apply spatial diversity reception . To solve this problem, we modeled it as an optimization problem with the constraint of the maximum false alarm probability of each channel and goal of minimizing the sum of misdetection probability over all the channels, and proposed two methods, branch and bound based method and greedy based heuristic method . The former can get the optimal strategy with high complexity, while the latter can reduce complexity obviously at the price of little loss of performance of detection and achieve a good trade-off between performance of detection and complexity .

Ri, Pyongyang University of Science and Technology, Pyongyang, Democratic People’s Republic of KoreaIt is very important to determine the location of handheld UHF RFID reader unit in the management of library or warehouse based on RFID system . In reality the management of the library or warehouse is performed in the 3D space . It is necessary to determine the location of handheld UHF RFID reader in 3D indoor environment .

Ting4, 1Syracuse University, Syracuse, United States, 2Xidian University, Xian, China, 3University carlos III, Leganes, Spain, 4University of Macao, Macao, ChinaThe future of computational electromagnetics is CHANGING DRASTICALLY with the new generation of com-puter chips which are multi-core instead of single core . Previously, advancements in chip technology meant an increase in clock speed, which was typically a benefit that computational code users could enjoy . This is no longer the case . In the new roadmaps for chip manufacturers, speed has been sacrificed for improved power consumption and the direction is multi-core processors . The burden now falls on the software programmer to revamp existing codes and add new functionality to enable computational codes to run efficiently on this new generation of multi-core processors . In this paper, a new roadmap for computational code designers is provided, demonstrating how to navigate along with the chip designers through the multi-core advancements in chip design . A new parallel out-of-core solver code termed HOBBIES using the Method of Moments (MoM) and higher order functions for expansion and testing will illustrate this roadmap .
