ELECTROMAGNETIC 3D SOLVER

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
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

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