Transform electromagnetic waves
and their constraints in terms of added value for our customers.

CAPITOLE-EM

The CAPITOLE-EM software allows you to study the electromagnetic behavior of your products in order to test your designs before the manufacturing phase. Simulation allows you to reduce the number of prototypes needed before launching your production and thus reduce your costs.

standard license
agile license customized by a specific development,
license increased by a study carried out by our engineers.CAPITOLE-EM simulates the electromagnetic fields of radiating devices such as antennas and their interactions with the structure (plane, car, frigate…). With a modern and intuitive graphical interface, it can be used in a wide variety of applications and provides fast and accurate results. Two modules: ANTENNA and SER are currently available to meet your needs in these fields of applications.
The new ACA-CBD solver, based on matrix compression, resulting from innovation projects supported by the DGA, is 10 times faster than conventional methods without any loss of accuracy and without any convergence problems.
