Hierarchical Electromagnetics
Fast electromagnetic designs and accurate full wave modelizations
Accurate EM models
Our unique Electromagnetic Modeler provides a circuital model
of a generic electromagnetic structure (microwave, optical ..).
The generated circuit preserves the fundamental properties (such as passivity, causality,
reciprocity..) of the actual device.
Pay for actual usage
There is no need of any upfront investment in hardware resources or sofwtare licenses.
Just subscribe to the Modelization Service which is delivered from the cloud
and you will be able to use as much computing resources as needed.
You will pay only for the actual utilization of the Modelization Service.
Fast Parallel Processing
Large electromagnetic structures (microwave circuits, array antennas ...) are often
created by assembling a large number of small parts.
These subcomponents are processed in parallel by independent instances of
the Electromagnetic Modeler. The generated subcircuits form a global circuit
which represents the complete electromagnetic structure.
Interoperabiliy
The equivalent circuits are more valuable than response curves
provided by traditional Electromagnetic Simulators and can be exploited
for any analysis in the time or frequency domain.
Being described in the standard Spice format they can be imported in most commercial simulators allowing an easy integration into a typical design flow.
Generic Decomposition
The Electromagnetic Modeler is based on a new numerical method which
extends the circuital approach to an arbitrary 3dimensional structure decomposed in
a number of subdomains.
Reusing of EM models
Quite often large electromagnetic structures (periodic array antennas,
Electromagnetic Band Gap strutures, Photonic Crystals ...) involve
a repetition of many identical parts.
These structures are analysed with a great efficiency by our Electromagnetic
Modeler because all the identical parts can share the same equivalent circuit.

EmCAD release 0.8.1 has been published
. New tests demonstrates very good accuracy
of the Hierarchical Electromagnetic Modeler in the simulation of passive networks
connecting active devices with excellent de-embedding of internal device ports.
18/03/2025
EmCAD release 0.8.0 has been published
with added GUI setting for searching impedance
poles also on real axis of Laplace plane.
01/03/2025
EmCAD release 0.7.9 has been published
which fully supports internal ports interfacing
active devices inserted in a passive electromagnetic structure.
Typical application case is de-embedding of monolithic circuits inserted in multichip modules.
EmCAD provides a very accurate simulation of this kind of EM structure which can't be properly
handled by other commercial solvers.
30/01/2025
The EmCAD release 0.7.8 has been published
Many improvements.
Going towards simulation of Multi Chip Modules.
Handling of some special ports inside MOR code need some corrections to be implemented in next release.
12/01/2024
The EmCAD release 0.7.2 has been published
Secure (verified) connection with the remote modeler service has been tested behind a firewall.
30/06/2023
The EmCAD release 0.7 has been published with many improvements and bug fixing.
An accurate algorithm was introduced for the computation of lowest frequency resonances defining the poles of the equivalent circuit.
Other poles (above a user specified threshold) are computed by the MOR code to assure an exact interpolation over a discrete set of frequencies.
The step files exported by the RealThunder Fork of the FreeCAD code (now the recommended CAD tool) are well suited for the definition of the geometric structure.
02/01/2021
New capabilities of filter design tool: custom (non canonical) ideal circuits and partial pre-distortion.
Improved processing of CAD data makes it possible to use geometries defined with ZW3D.
02/06/2020
A deep rewriting of the Electromagnetic Modeler with the introduction of a more efficient method
for the generation of the low level (mesh related) equivalent circuits.
This release brings a great improvement in the usability of the EmCAD tool with
a smaller effort required from the user side for the preparation of the problem data.
14/01/2016
A new release of the Electromagnetic Modeler brings new tools for the design and tuning of microwave filters.
