CEM One
A Complete Environment for Computational Electromagnetics (CEM)
CEM One is a consolidated software package with its first commercial shipment in December 2012, combining the best of Computational Electromagnetics, namely PAM-CEM Simulation Suite and Efield Solutions.
PAM-CEM Simulation Suite operates mainly from medium to high frequency range. When targeting a wide frequency spectrum as usually managed with EMC/EMI issues, time-domain techniques are applied to investigate electromagnetic phenomena appearing along those complex cables networks connecting onboard electronics.
Efield Solutions is primarily frequency-domain oriented with focus on antennas and scattering, making the overall solution fully consistent. ESI acquired Efield end of the year 2011.
The consolidated solution emphasizes a coupling and hybridization strategy, extending much beyond previous limits with larger models, higher operating frequencies, and more sophisticated scenarios, taking electromagnetic modeling one step further.
