EM3DS (Electromagnetic 3D Solver) is at its 12th editions,
improving
and adding features to its portfolio. EM3DS 12 implements
extended
parametric features, additional editing utilities and several
time-domain
tools. EM3DS 12.1 -in spite of being labeled still as version
12- is a major
breakthrough, as EM3DS has been completely updated with new
technology and it is now 64 bit, featuring 30% and more higher
speed
and unlimited memory capability.
A macromodel builder, a very useful tool to speed up the circuit
design,
is also included.
EM3DS is a frequency-domain full-wave simulation tool tailored
to
efficiently accomplish the analysis of quasi-planar structures
specifically planar structures over complex substrates, where the
finite conductors'
thickness and the dielectric discontinuities are accounted for
with no
compromise thus, rendering EM3DS a full 3D tool.
Unlike most Method-of-Moment (MoM) solvers available on the
market, it
uses volume currents to account for conductors and dielectric
bricks
(generally MoM solvers are 2.5D in their very nature, using only
surface
currents). This feature allows modeling Dielectric Resonators,
bulk
acoustic wave resonators (FBAR), active linear Field Effect
Transistors, as well as standard MMIC and printed circuits,
filters.
New internal ports are specially useful for modeling packages.
The new
charts and calculation of far field make EM3DS 2011 suitable for
planar
antennas.
An Object Oriented Pascal Script is added to allow customization
of the
EM3DS and direct access of EM3DS features
EM3DS also features a 2.5D engine, making easier and faster
to
correctly setup robust electromagnetic simulations.
Definition of structures in EM3DS is done layer by layer in the
main 2D
graphical window - however there are several 3D visualization
windows
to check the design and where to see induced currents.
EM3DS can also import layer structures in the BMP, DXF and
GDSII
formats from mechanical drawing software. All parameters,
dimensions
and material constants can be defined using mathematical
expressions, and may be used to run automatic full-wave
optimization
Various ports and port calibration can be defined,
characteristic
impedances for (un)coupled transmission lines are computed.
By using the proprietary Asymptotic Estimation Algorithm
(extracting
most of the information from a single frequency analysis), and
the
SmartFIT tool, wide-band simulations are performed very
fast.
