Computational Electromagnetics Code Validation and the Electromagnetic Code Consortium: Case studies, challenges, lessons learned, and recommendations.

We examine validation of computational electromagnetic (CEM) codes through the lens of the Electromagnetic Code Consortium (EMCC), a group of U.S. government and associated CEM practitioners that was active from the 1980s through the 2010s. Available EMCC validation cases are summarized, and several practical validation challenges, lessons learned, and recommendations are provided. Finally, one of the original EMCC cases, the metallic “business card,” is revisited to illustrate some challenges of matching modeled and measured results and their possible resolution. An integrated team-based approach to constructing validation cases and diagnosing discrepancies between modeled and measured data is recommended.
