This recommended practice is a companion document for IEEE Std 1597.1-2008.1 It provides examples and problem sets to be used in the validation of computational electromagnetics (CEM) computer modeling and simulation techniques, codes, and models. It is applicable to a wide variety of electromagnetic (EM) applications including but not limited to the fields of electromagnetic compatibility (EMC), analysis of radar cross section (RCS), signal integrity (SI), and the analysis of antennas. This document shows how to validate a particular solution data set by comparing it to the data set obtained by measurements, alternate codes, canonical, or analytic methods.
