## Abstract The multilevel fast multipole algorithm (MLFMA) is applied to the problem of a general three‐dimensional dielectric target above or below a lossy half space. The dyadic half‐space Green's function is evaluated rigorously for the “near” MLFMA interactions, while an asymptotic Green's fun

✦ Synopsis
Dyadic Green's functions for a dielectric half-space, based on ''Formulation C,'' are computed by a fast algorithm using the discrete complex image method with a two-le¨el approximation. The results show ¨ery good agreement with those calculated by direct numerical integration. It is expected to be used for the analysis of radiation and scattering from targets buried underground.

## Abstract There has recently been significant interest in the method‐of‐moments (MoM) and fast multipole method (FMM) for the analysis of scattering from targets in the presence of a lossy dielectric half space (soil). It is desirable to make the analysis of scattering from such a target consiste
## Abstract In this article, the electromagnetic analysis of arbitrarily shaped three‐dimensional homogenous dielectric objects located above a lossy half space is considered with a well‐conditioned surface integral equation. The electric‐magnetic current combined‐field integral equation (JMCFIE) i
