Influence of inhomogeneities in a stratified ground on the field of a circular loop antenna
This paper extends earlier works on three-dimensional scattering from a finite obstacle in a stratified halfspace, treated by means of the T-matrix method. In this paper we consider a general source configuration above the ground, that excites the subsurface medium and its inhomogeneity. Explicit expressions are given for the magnetic dipole, the circular, and rectangular antenna loops. Numerical
