Electromagnetic Emissions and Mitigation Design Software Modeling Service

ELEXANA – Precision Modeling for Safer, Cleaner EM Environments


Elexana now offers advanced electromagnetic modeling and mitigation design services, enabling clients to visualize, assess, and refine electromagnetic field behaviors before physical prototypes or installations are completed. Using industry-leading simulation platforms such as ANSYS HFSS, CST Studio Suite, and COMSOL Multiphysics, we simulate EM propagation and shielding behavior across frequencies ranging from DC to 100 GHz and beyond.

This service is essential for developers of electronic products, antennas, PCB assemblies, high-voltage systems, and critical infrastructure, including transformer vaults, substations, and hospital equipment.
