Electromagnetic fields of electric dipoles embedded in a stratified anisotropic Earth

Abstract

Abstract The anisotropy of electrical conductivity in earth formations may be caused by crystal anisotropies of minerals, as well as by minilayers which occur frequently in sedimentary environments. The effects of anisotropy on the propagation of electromagnetic (EM) fields have been studied by many geophysicists. For instance, Kong (1972) and Wait (1981) solved the EM propagation problem for vertically anisotropic layered earths; O'Brien and Morrison (1967), for a horizontally anisotropic multilayer half-space; Chetayev (1960), as well as Reddy and Rankin (1971), for media of dipping anisotropies; and Al'tgauzen (1969), for more complicated anisotropic media with a tensor dielectric constant of five components.
