PAM-CEM Simulation Suite Version 2009.0 from ESI Group is an electromagnetic software package for full virtual testing. Together with the very first Visual-CEM dedicated environment, issued earlier in 2009, the PAM-CEM 2009.0 release helps users analyze and design within a continuously expanding electromagnetic spectrum. The PAM-CEM Simulation Suite offers industrial coupling capabilities to fully address realistic models in their early design stage and to assess real electromagnetic multiscale phenomena occurring in the middle- and high-frequency ranges. Its ability to handle fully equipped 3-D models featuring on-board complex antennas, as well as realistic cable networks, is of benefit to end users. This latest release includes several key enhancements of benefit for transportation, aeronautics, and defense industries. The overall performance, including graphical user interface and ease of use, has been significantly improved in this latest release with the development of Visual-CEM 5.5, a dedicated user environment allowing the management of billions of unknowns, leading to higher operating frequencies.
