Electromagnetic scattering from subterranean obstacles in a stratified ground

In English In this paper we give a general three-dimensional treatment of electromagnetic scattering from a finite obstacle in a stratified half space. The two generic cases of an obstacle either below all layers or inside one of the layers are treated. The results are an extension of earlier works on scattering in related geometries, treated by means of the T matrix method. Numerical results are presented for subterranean inhomogeneities of various shapes in a lossy one-layered half space with plane interfaces.
