7. ELECTROMAGNETIC 3D SOLVER 12
TOOL 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...

21. Electromagnetic 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

22. Components
Directional coupler: designed for application in the mobile phone market
