The Challenge of Numerical EMC

Alt Text

With the increasing use of on-board electronic equipment, mastering EMC compliance in the early design stage is becoming a critical technical issue. Numerical EMC is appearing as a promising way to make it faster and cost-effective. This is one major challenge for Computational Electromagnetics.


PAM-CEM Solutions is a software package aimed at performing realistic and predictive ElectroMagnetic Compatibility (EMC) simulations in the transportation industry, automotive and railways, in Aeronautics and Defense, in Telecommunications and in Electronics. Developed by a team of specialists who have focused their research efforts on electromagnetic simulation for the last 25 years, PAM-CEM Solutions are specifically designed to simulate EMC testing. The PAM-CEM scope is ranging from ElectroMagnetic Interference (EMI) to ElectroMagnetic Susceptibility (EMS) of electronic systems or products. Electromagnetic pollution of large harness systems is also relying in the PAM-CEM application field. The objective is to exploit PAM-CEM simulations within the early stages of design development, in order to predict possible functioning problems, and take immediate actions, before even reaching the test phase.

PAM-CEM Features

With the aim of addressing fully realistic models in their early design stage, PAM-CEM Solutions are proposing

A dedicated environment enabling the specification of all EMC relevant features in one shared model starting from native CAD data or from existing meshes,

Specialized capabilities for wires, bundles and cabling, from a simplified harness to a fully industrial Cable Network featuring more than a thousand wires,

Dedicated functionalities for the simulation of realistic models featuring lossy dielectric grounds, wired exciting antennas, absorbing materials, etc.

An advanced 3D explicit software product, PAM-CEM/FD, operating directly in time domain and allowing the fast investigation of electromagnetic phenomena, developed from the widely used Finite-Difference Time-Domain method
