AlbuquerqueLeland Bowen, the Chapter Chair for thejoint AP/EMC/MTT/NPS Chapter,reports that the Chapter was very activethis Fall. In August, Dr. Jamesina J.Simpson, Assistant Professor, Depart-ment of Electrical and Computer Engi-neering, University of New Mexico, gavea presentation entitled, “ComputationalElectrodynamics Modeling from Near-DC to Light.” Fifteen people, includingfour EMC Society members, were inattendance. In late October, a talk enti-tled, “Plasma and Megagauss Fields” wasgiven to the Chapter by Dr. Peter J.Turchi, Los Alamos National Laboratory,IEEE Fellow (NPS Distinguished Lec-turer). Twelve Chapter members enjoyedthe presentation, including seven EMCSociety members. In November, theChapter enjoyed a presentation entitled,“Practical Aspects of Microwave FilterDevelopment.” The talk was given byDr. Richard V. Snyder, RS Microwaveand the New Jersey Institute of Technol-ogy, and enjoyed by 10 Chapter mem-bers. To cap off a great year, the Chapter

enjoyed a New Year’s Eve party at Dr.Carl Baum’s residence. The 12 Chaptermembers at the party enjoyed plenty of“Good food, including sushi, good socialtime, good music and good drink” in a“highly non-technical” environment.

Chicago Jerry Meyerhoff, secretary of the ChicagoChapter reports that theChapter was very busythis last Fall. Chicagoheld its fall season kick-off meeting on September19 hosted by DLS Elec-tronic Systems. Themeeting focused on areview of the 2007 50thAnniversary Symposiumin Hawaii. Jerry Meyer-hoff, Continental Auto-motive Systems, deliv-ered a breezy slide showon representative techni-cal subjects, committeeactivities, exhibits and

social events - complete with photos. RoyLeventhal of Leventhal Design & Com-munications also shared his experiencesduring the open discussion. Then, DonSweeny of DLS and Chapter Angel pre-sented his condensed version of theimpressive “History of EMC“ CD, whichis an IEEE EMC Society slide show.

Special ESD Test from Down UnderDan Hoolihan has been practicing in the EMC arena for morethan three decades. The following story falls into the ‘strangebut true’ category that experienced EMC engineers, such asDan, always have a number of in their files. How would usersreact today with these kind of operational instructions?

“Back in the 1970s when electrostatic discharge (ESD) andits impact on electronic equipment was first being researched,many companies were experimenting with various ways to testequipment for ESD susceptibility. Since “standard” ESD gen-erators were not available, many companies developed theirown generators including small Van de Graaff machines, lab-built generators, and standard nylon carpets.

A low-cost computer terminal (an electronic stationdesigned to allow a person to communicate with a large, high-speed mainframe) was developed by a computer company inthe United States. The terminal was successfully designed,tested for conformance to internal corporate specifications, andwent into production. The design verification testing includ-ed both emission and immunity testing for EMC performance.One of the immunity tests was an ESD test using a “standard”nylon carpet that the tester would shuffle his feet on and mea-sure about 5 kilo volts (with a sensitive electrostatic voltmeter)

before discharging himself to the unit under test. The termi-nal passed the test and was used successfully around the worldexcept in Australia.

In Australia, the terminal had consistent ESD failures. Inattempting to trouble-shoot the problem, an engineer fromAustralia came to the United States and worked with thedesign engineers. The computer terminal was placed in a largeenvironmental chamber and the relative humidity was loweredto about 10% for a worst-case test of ESD. The engineer fromAustralia stepped on the “standard” nylon carpet, shuffled hisfeet and the electrostatic voltmeter measured 15 kilovoltsinstead of the usual 5 kilovolts, and, of course, when he dis-charged to the terminal, it failed.

The design engineers were amazed at the amplitude of thevoltage and started to quiz the Australian on what he wasdoing or what clothes he was wearing. He convinced thedesign engineers he had on “normal” clothing except for hiskangaroo leather shoes!

The company had a choice of coming up with a special fixfor the product for Australia or outlawing kangaroo leathershoes. They chose to recommend to their Australian customersto preclude the wearing of kangaroo leather shoes if they want-ed to avoid ESD problems with the low-cost terminal.”

Edgar also shared his insights intothe regulatory and technical processesbehind frequency band assignments inthe FCC and industry associations. EliteElectronic Engineering, who offered theirtraditional Oktober-fest style hospitality,hosted the November 14 meeting. Theannual election of officers went smoothlyfrom the slate organized by Roger Swan-berg of DLS. The meeting was a very wellattended joint session including regionalSAE and Fox Valley IEEE Section mem-bers. Bernie Sander of the IEEE ChicagoSection briefly addressed the group. Thefeatured speaker, Steve Laya of Elite,spoke on the MIL-STD specifications andprocesses. It was fascinating to gain anunderstanding of the interplay betweensubsystem suppliers and master contrac-tors. These three groups need to worktogether to optimize the EMC specifica-

tions and performance for the vehicle as awhole, depending on its mission: air, seaor ground. The 6th Annual HolidayParty on December 11 was again orga-nized by Ida Krozel and held at Dave &Busters in Addison. A DeVry UniversityEE Professor and his students happilyjoined us. The buffet dinner was followedby the Holiday Jeopardy-Trivia wordgame by Ray Klouda of Elite. The bil-liards tournament, organized by ChapterChair Jack Black of DLS, brought out allthe sharks.

(http//www.fesb.hr/SoftCOM/2007). TheCroatia Chapter was the co-organizer ofthis conference, too. To illustrate the pro-file and the quality of these eventsachieved up to now, following are somedetails about the 2007 Symposium onEMC and SoftCOM Conference.Researchers and experts from industry,research institutes and universities from30 countries submitted 150 papers for theConference. All papers have been carefullyvalidated in the review process with some65% accepted for presentation, which wassuccessfully done thanks to more than 180scientists from all over the world. TheConference had more than 200 partici-pants. By organizing the EMC Sympo-sium in conjunction with this Conference,the quality was upgraded in the technicalsense and the number of the participantsincreased. Also, such Symposium organi-zation was helpful in improving the coop-eration between the researchers from acad-emia, industry and government from theEMC and Communication communities.The Chapter members and guests had theopportunity to attend the presentations ofthe distinguished lecturers and invitedspeakers. For instance, over 150 attendeeswere present during the excellent report

titled “Technology Evolution: FuzzierBoundaries Broader Opportunities” givenby the keynote speaker Dr. Roberto Sarac-co from Telecom Italia, IEEE ComSoc Sis-ter Societies Director. At the Symposiumon EMC, 13 contributions were reportedwith two invited presentations. Some 25%of the submitted papers were not accepted.One tutorial was held and the round table“Ask the Experts” was organized. The best

student paper competition was organizedwith one of the Symposium papers beingawarded. The best Symposium papers willbe selected and the extended versions willbe recommended for publication in theJournal of Communications, Software andSystems (JCOMSS, Journal of the SisterSociety of IEEE ComSoc). The Chapter isvery much thankful for the support andvaluable technical contributions from the

Croatia Chapter members and friends arriving on Karaka to the oldDubrovnik harbor.

President of the IEEE EMC Society, Mr.Andrew Drozd, and the President-Elect,Mr. Elya Joffe. Their significant contribu-tions directly increased the quality of theSymposium. Twenty-seven Chapter mem-bers and guests had the opportunity toattend very interesting and instructivepresentations about ElectromagneticDiversity given by Andrew Drozd as wellas his President’s State of the EMC SocietyMessage. The Chapter is especially thank-ful to its Angel Elya Joffe for his valuablesupport in organizing the Symposium aswell as his great contribution during theSymposium. His well attended tutorialtitled “Grounding, the Essence of theEMC Design” was very interesting for allin attendance, not only for the EMC mem-bers. Over 30 attendees showed a greatinterest in these two presentations accom-panied with experiments and demonstra-tions. The technical presentations werecompleted with an intensive informal dis-

cussion during the meeting “Ask theExperts” on EMC topics, which was heldon the conference ship while sailing fromSplit to Dubrovnik. Pleasant social eventswere organized in both conference towns.The participants and their guests enjoyedreceptions given by the mayors of Splitand Dubrovnik, respectively. In Split, ashort concert of the local Dalmatia washeld in the Basement of the DiocletianPalace (a monument listed as theUNESCO World Heritage). While travel-ing from Split to Dubrovnik by ship, theparticipants had the opportunity to enjoythe beautiful landscape of the Dalmatiancoast. In Dubrovnik, the participants wereable to experience a piece of history whilesailing around the old Dubrovnik walls inthe 15th century replica boat “Karaka.” Apresentation of the IEEE and EMC Chap-ter has been traditionally organized duringthe Career Day in the frame of the FacultyDays at the University of Split, FESB.

Similar action promoting the interests ofthe IEEE and EMC Society was also orga-nized during SoftCOM 2007 at the pro-motional booth.

Hong KongThe IEEE Hong Kong EMC andAP/MTT Chapters enjoyed a successfulmeeting on November 6. Dr C-K Chou,Chairman of IEEE International Com-mittee on Electromagnetic Safety - Tech-nical Committee 95, gave an interestingtechnical presentation on the topic, “RFBio-Effect Research to Address HumanSafety Concerns.” The IEEE Hong KongEMC Chapter held a very successfultechnical event on December 15. On thatdate, Mr. Elya B. Joffe addressed twoEMC topics of EMC principals and prac-tices that were enjoyed by 25 attendees.Specific topics addressed by Mr. Joffeincluded 1) Current, if not obstructed,

JapanMore than 100 EMC professionals inJapan joined a meeting in Sendai onOctober 25, 2007 to celebrate thirtyyears of EMC research activity in Japan.The two Chapters, one in Sendai and onein Japan, started in 1977. A research andtechnical meeting of Japan, the TechnicalCommittee on EMCJ Institute of Elec-tronics, Information and Communication

Engineers (IEICE), is helping with itsmonthly activity. Also, the EMC SendaiSeminar marked its 179th technicalmeeting recently. Special lectures camebefore the ceremony. Professors RisaburoSato and Tasuku Takagi talked on topicsrelated to the birth and growth of EMCresearch in Japan and its history over thepast thirty years. After the commemora-tive lectures by these two forerunners,Professor Masamitsu Tokuda talkedabout his recent research in EMC as anew IEEE EMC Society Fellow. The 30thanniversary event was a warm and brightceremony. The two meeting Chairs, Pro-fessors Hiroshi Inoue (Akita University)and Hideaki Sone (Tohoku University),expressed their thanks to many people inthe research field of electromagneticcompatibility. Eight researchers, whowere successive chairpersons of theEMCJ, Professors Masamitsu Tokuda,Shuichi Nitta, Yoji Nagasawa, AkiraSugiura, Yoshio Kami, Hiroshi Echigo,Youji Kotsuka and Ryuji Koga, receivedawards recognizing their contribution toestablishing EMC activity in Japan.

Long IslandDavid W. Sterner of the Long IslandChapter reports that in 2007 they had sixmeetings, including a presentation atLISAT 2008 (Long Island Systems Appli-cations and Technology Conference).Topics included antenna characterization,Mohr on minimizing crosstalk in wiringand cabling, performance characteristicsof capacitors, metalization of plastics, andtechniques to reduce conducted emis-sions in a power supply. At IEEE EMC2007, Anthony Zimbalatti representedthe Chapter and was honored as one ofthe Founders of the IEEE Electromagnet-ic Compatibility Society. The officers for2008 are Tom Schneider, Chairman, andDon Lerner, Vice Chairman.

Central New EnglandJohn Clarke, Secretary, reports that theChapter held a meeting on Wednesday,November 7. The speaker was Douglas C.Smith of D.C. Smith Consultants in LosGatos, California. The presentation cov-ered the topic “Locating ESD and otherImpulsive Events using the Speed ofLight.” Modern electronic equipment canbe much more susceptible to impulses inthe environment or even on the sameprinted wiring board. At the same time,digital oscilloscopes now can single shotsample a waveform at 40 gigasamples/sec.Methods of using high-speed scopes totrack down sources of noise in a room or ona circuit board were described. Several“war stories” were shared with the audi-ence to illustrate the point. Also, experi-ments were conducted with volunteersfrom the audience in order to demonstratethe phenomena described. Twelve peopleattended the November meeting, includ-ing 11 IEEE members and one guest. Dur-ing calendar year 2007, the Chapter wasonly able to schedule the minimumrequirement of two meetings - on April 17and November 17. However, the Chapterwas also a Co-sponsor of the nationallysuccessful Tech Tour, held at the WestfordRegency Hotel and Conference Center onJune 19. Chapter members Lee Hill andRandal Vaughn were two of the speakers.Chapter Chair Boris Shusterman repre-sented the Chapter at the 2007 IEEEInternational Symposium on EMC inHawaii. This year, the Chapter willresume its normal schedule of three or fourmeetings. Boris has been in contact with anumber of potential speakers for 2008.

New Jersey CoastChrishna Raghunandan, Chapter Chair,reports that the New Jersey Coast Chapteractively presented four technical talks thatwere very well attended. The first twotalks were held at the Infoage Museum inWall Township. This museum was anactive site that supported military com-munications through the Second WorldWar and later. There was a brief introduc-tion to the museum and its artifacts by itscurator prior to the IEEE talk. OnNovember 11, 2007, Elya Joffe gave apresentation entitled, “Don’t Want a CellTower Near Your Home?” His talk cov-ered a topic that caught a lot of publicattention. The talk was well attendedwith many representatives of townshipboards who were actively consideringtowers in their townships. The presenta-tion brought a lot of detailed material yetwas presented with a good sense of humorto keep such a controversial topic bothhonest and down to earth. Slides weremade available on the New Jersey coastweb site prior to the talk so that manymembers of the public, who could notattend, could benefit from the material.The same day, Elya also spoke on, “Fre-quently Asked Q & As on EMC and PCBDesign.” This was a hands on technicaltalk that presented commonly encoun-tered questions on how to design circuitsand systems keeping EMC in mind. Thistalk was very much appreciated by activedesign engineers. The talk was kept high-ly interactive with many questions fromthe audience on do’s and don’ts that werepresented during the talk. On November30, Krishna Raghunandan gave a presen-tation entitled, “Environmental Effects ofWireless Radiation.” This was a compan-ion talk to the first talk and covered factsand figures from a variety of standardsbodies including the IEEE. The talkfocused on engineers who were involvedin the design of antennas and towers andhad to respond to townships or otheragencies. The talk brought to light typi-cal power levels used by communicationtransmitters today and correspondingpower levels of hand held devices used bythe public. The talk was well received andthere were many questions from the audi-ence. On December 12, 2007, AmitMukhopadhyay gave a talk regarding,“Cell Phones on Board Airplanes.” Thistalk addressed the issue of using cellphones on board commercial aircraft.Technical issues concerning how different

service providers intend servicing cus-tomers were discussed. It brought to lighta variety of safety concerns as well as ser-vices that were offered until recently andwhat is likely to be offered in future. Thiswas an illuminating talk not only for thefrequent flyer, but also for engineers whoneed to work through many agencies tomake such systems operable. Slides of theNew Jersey Coast meetings are availableat: http://ewh.ieee.org/r1/njcoast/ Clickon the talk’s title after selecting “calendarof events.”

Orange CountyJeff Klinger, Chapter Chair, reports thatthe Orange County Chapter resumedmeetings after the 2007 summer breakwith a very interesting and well attendedpresentation by Jack Unger, of Ask-wi.com, on the wireless internet serviceprovider (WISP) industry. His talkfocused on the need for FCC complianceon the hardware that is being assembledfrom radios that are mostly not approved,or only partially approved, in a very lim-ited fashion. Other topics from this pre-sentation included the progress and stateof WiMAX and the effect on the WISPindustry. In October, Mathieu van denBergh, of CNS Inc. Poway, California,gave a very rich and informative presen-tation on “Compliance testing for lowvoltage power line immunity and low fre-quency emissions of electrical products.”Electrical products are used in just aboutevery industry segment and need to betested to assure they are immune to com-mon disturbances occurring on the pub-lic low voltage supply system. Also, elec-trical products offered for sale in Europeand most Asian countries must meetemissions standards; that is, they cannotinject too many current harmonics orcause excessive voltage fluctuations of thepublic supply (100/120/220/230 V-rmsat either 50 or 60 Hz). The presentationby Mathieu van den Bergh included dis-cussions on test methods, equipmentneeded for the tests, and some case histo-ries of measurements and problem resolu-tion with tested equipment. In theprocess, measurement standards, such asIEC61000-4-7 and IEC61000-4-15,which apply for these compliance tests,were reviewed in great detail. Upcomingamendments to both measurements stan-dards were presented. Also, amendmentsfor IEC61000-3-2/12 and 61000-3-3/11

PhoenixGlen Gassaway reports that the fallmeeting included the election of Chapterofficers for 2008. After some discussion,the Chapter voted to retain the existingofficers for another year. Harry Gaul thenintroduced our featured speaker, JoeButler of Chromerics. Joe is also a Past-President of the IEEE EMC Society. Joestarted his presentation on shieldingeffectiveness testing of EMI shieldingmaterials (such as EMI gaskets, paints,shielded windows and vents) by men-tioning that the industry does not have aconsensus standard in place. Rather, thetest methods for shielding effectiveness

range from variants of the long agoretired MIL-STD-285 to the more recentIEEE-STD-299. For military orientedproducts, the shielding data is quiteoften a result of a modified MIL-DTL-83528 test method. Although Joedescribed several shielding test methodsfor various products from varioussources, the majority of shielding effec-tiveness data tends to be derived fromradiated field-testing methods. Whilemany large corporations that have EMCgroups on staff may use transfer imped-ance and reverberation chamber testmethods due to their more inherentaccuracy and repeatability, most vendorsof shielding components have not fol-lowed their lead. The reasons for this dif-ference in approach run from factors suchas lack of resources, the comfort level ofthe vendor’s EMC engineers in interpret-ing the internally generated data, to theinherent frequency limitations of theselatter test techniques when contrastedagainst the market need for 30 MHz to40 GHz shielding effectiveness test dataneeded to market the products. Currentstandards activities include revisions toIEEE-STD-299, generally creating threemethods based on enclosure size. Theseactivities are trending more towardsreverberation chamber techniques, gen-erally thought of as the most accurate.Unfortunately, these techniques maygenerate test data that makes shieldingproducts look ‘worse’ than presentlyused methods. For this reason, as well ascost and resources, most shielding man-ufacturers have not yet incorporatedreverberation techniques as part of theirmaterial test programs. Joe mentionedthat some customers have recently beeninterested in assurances of long-termreliability through post environmentaltesting (such as ALT). The industry is

also interested in 94V-0 flammabilityratings, RoHS and other “green” initia-tives. Customers have requested elemen-tal analyses of various products. Materialshielding effectiveness using moderntrivalent coatings (MIL-C-5541F) hasalso been an issue. Some agree that newstandards are needed for these trivalentcoating techniques.

PittsburghA meeting of the Pittsburgh EMC Soci-ety Chapter was conducted on October25, 2007 at the Westinghouse EnergyCenter in Monroeville, Pennsylvania.Michael Oliver, IEEE EMC ChapterChair and Harry Godlewski, Vice Chair,hosted the meeting with 12 IEEE mem-bers. The meeting started with a socialprior to a technical presentation. We hadthe privilege of having Steven Ferguson asour technical speaker; Steven is the VicePresident of Operations with WashingtonLabs. Initial discussions encompassedEMC related job openings from tworecruiting companies, Enlow & AssociatesInc. ([email protected]) and HBECorporation ([email protected]).The upcoming technical presentationagenda and an introduction of Mr.Steven Ferguson was then announced. InStevens’ career, he has worked on thespace shuttle, Hubble telescope, andmany other high profile jobs performingand/or coordinating EMC testing. Thetechnical presentation by Steven is titled“MIL-STD-461E (F) Requirements andTechniques.” This presentation is basedupon the military standard and its newrequirements along with the expert

product testing experience that Stevenbrings to his audience. Steven discussedEMC testing per MIL-STD-461E withemphasis on requirements for documen-tation (the DIDs), instrumentation, andpreparation of the test article. A briefoverview of each test method was includ-ed along with advice about tailoring forthe unusual test. Such an overview ofMIL-STD-461 is helpful to the test engi-neer to enable better understanding ofthe test data. In addition, this overviewhelps the design engineer to understandwhat could happen to his product duringthe testing. MIL-STD-461, revision F istentatively scheduled for release near theend of October; the presentation includ-ed these proposed changes in comparisonto revision E. As the Vice President ofOperations, Steve Ferguson is responsi-ble for the day-to-day testing and engi-neering activities at Washington Labs.He also prepares control plans, testplans, and test reports to guide thedesign from concept to qualification testacceptance for DoD and commercial pro-grams. He has over 28 years of experi-

ence in the EMC area with prior man-agement positions for US Governmentand commercial electronics manufactur-ers. At times, he can be found in the lab-oratory or on-site performing a test orpresenting a hands-on course in testingper MIL-STD-461.

Rocky MountainMeeting in Westminster (northern sub-urb of Denver), the Rocky MountainChapter of the EMC Society (RMCEMC)continues to have a strong program witha wide variety of EMC related topics. TheChapter was the first to try out the Webi-nar technology for an EMC Distin-guished Lecturer technical presentation.On October 9, EMC Society Distin-guished Lecturer Dr. Jun Fan (of the Mis-souri Institute of Science and Technolo-gy) presented a talk to the Chapter on“Power Distribution Network Design forHigh-Speed Printed Circuit Boards”using the Webinar technology. Dr. Fanpresented from Missouri; 80% of the par-ticipants met in Westminster, Colorado;

and the last 20% of the Chapter partici-pants participated from as far as a two-hour drive away from Westminster. Thisformat was well received especially forthose people that live and work far awayfrom our normal Chapter meeting loca-tion. Admittedly, on-site speakers alwayshave the advantage of more informalinteraction with the speaker before andafter the actual presentation, but theWebinar allows more presentations to bemade worldwide for minimal cost. Forthis meeting, we also implemented a newonline survey using SurveyMonkey ser-vices that made entering and collectingthe survey data much more efficient. OnOctober 30, Mr. Ian Dodd provided anon-site technical presentation on “Multi-Gbps Channel Analysis for the IC andSystem Level Designer.” Then on Decem-ber 3, Mr. Otto Buhler gave a presenta-tion on “Power-Ground Plane TransientImpedance.” He provided some insight-ful conclusions regarding the limits of use-fulness of the imbedded capacitance andappropriate implementations of decouplingcapacitance. The slides and papers from

SeattlePat André, Chapter Chair, reports thatthe Seattle hosted a four-hour, afternoon

meeting on October 10, 2007. Thespeaker was Dr. Bruce Archambeault,Distinguished Engineer from IBM(Research Triangle Park, North Caroli-na), and the author of the book “PCBDesign for Real-World EMI Control.”Dr. Archambeault gave two talks duringthat time, “The Ground Myth” and“Proper Decoupling Strategies for BothEMC and Signal Quality.” The talkswere very well attended and received.With a lively crowd and a hearty lunch

provided by CKC Laboratories, atten-dees enjoyed an afternoon of fellowshipand a highly informative discussion. Dr.Archambeault is always well receivedand most entertaining to listen to, and isable to make Maxwell’s equations easy tounderstand. His board layout techniqueschallenge the status quo, but are sup-ported by sound physics and muchresearch. In support of the Society, GeneGarat of Moss Bay EDA supplied threeIBM thumb drives to be given away as
