Progress on the development of standards and recommended practices for CEM computer modeling and code validation

Progress towards the development of standards and recommended practices for computational electromagnetics (CEM) computer modeling and simulation and code validation is discussed in this paper. This has been a topic of recent interest within the electromagnetics community. The relevant areas addressed include printed circuit board radiated and conducted emissions/immunity, system-level EMC, radar cross section (RCS) of complex structures, and the simulation of various electromagnetic environment effects (E/sup 3/) problems. In particular, there are concerns regarding the lack of well-defined methodologies to achieve code-to-code or even simulation-to-measurement validations within a consistent level of accuracy. This paper describes projects that are underway to guide the validation of CEM application models.
