Abstract

The fast multipole method (FMM) was originally developed for perfectly electric conducting (PEC) targets in free space. Here, the FMM is extended to the scattering from a PEC target above or below a lossy half space. The “near” terms are handled via a method-of-moments (MoM) analysis, wherein the half-space Green´s function is evaluated through application of the method of complex images. The “far” interactions utilize an approximation to the Green´s function dyadic. The algorithm is validated through comparison with rigorous MoM results
