摘要

快速多极子法(FMM)最初是针对自由空间中完全导电(PEC)目标而发展起来的。在这里，FMM扩展到从有耗半空间以上或以下的PEC目标散射。“近”项通过矩量法(MoM)分析处理，其中半空间格林函数通过应用复图像方法进行评估。“远”相互作用利用格林函数二进的近似。通过与严格的MoM结果对比，验证了算法的有效性。

Fast multipole method for scattering from an arbitrary perfectly conducting target above or below a lossy half space

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.
