Advanced research: • Entirely developed by a research team, includes many unique features (controlled current sources, multimode calibration, ability to enter

any frequency dependent parametric expression to describe new materials, interaction with acoustic waves: investigate the impact of material properties (electrical, mechanical), new electromagnetic phenomena and devices, develop your own calibration technique for measurements, time-domain feature

• A Pascal Object-Oriented scripting let you handle directly internal parts of EM3DS! Create your own menu in EM3DS, link to events/parameters/results

• It is 3D: simulate at the same time dielectric resonators, planar circuits, active linear devices

Acoustic modeling Scripting

EELECTROLECTROMMAGNETIC AGNETIC 3D3D SSOLVER OLVER 1212TOOL OF CHOICE FOR

Design of RF, Microwave, mmWave and MEMS circuits: • Flexible: Parametric definition of objects and materials; you can tune, modify, optimize parameters; extract a parametric macro-model (real-time estimation of response as a parameter is

changed); create macro-commands by a pascal script; no grid to fit into...• Very Fast: Asymptotic extraction technique (fast for many frequency calculation), Variational (coarse mesh gives good results as well), SmartFIT selects automatically and adaptively

frequencies to catch and plot resonances; uses a Method of Moments: only conductors are meshed (insensitive dramatic cross-sectional aspect-ratio), and complex substrates, including tents of layers, are quick and easy to simulate

• Very Powerful: Allows a broad class of devices: microstrip, stripline, coplanar waveguide, coupled strip based components, filters, couplers, planar antennas and array of antennas, dielectric resonators, acoustic resonators, active linear devices (MESFETS, HEMTS), transitions, matching circuits

• Complete suite: includes many kind of charts (Smith’s, polar antenna, S/Z/Y/losses/VSWR/Phase difference/Q measurement, contour plot, surface plot of currents/field, far field plot, 3D views etc); a linear circuit simulator to attach sub-circuits, connect lumped elements, manually calibrate etc; a broadband spice model extractor: extract equivalent circuits automatically; import/export results in touchstone format; filters to import/export GDSII and DXF structures...

Electromagnetic modelingElectromagnetic modeling

Purpose: evaluate the electromagnetic field distribution across “planar” and “quasi-planar” structures when a sinusoidal electrical signal is applied somewhere -the point of excitation is a “port”

What planar means: a structure which is entered layer-by-layer, as common in semi-conductor technology: e.g. microchips, printed circuit boards, microelectromechanical devices
