Numerical methods in electromagnetics, coupled with faster computers have led to more complex and complex models. However, it must be remembered that these are models; and as models, they are purely representations of reality. In many cases these complex approaches can take several days to solve and, while really accurate, they fail to model the extremely complex components of an anechoic range. RF absorber is the most important of these components and it can be shown that it is in itself a very complex material that is not easily modeled without approximations. A simple approach that effectively “models” an anechoic room was presented in the past, and while its results may not be accurate like some of the other numerical methods, it provides the designer with a quick result that can help in making design decisions.
