Theory of radiation from sources immersed in anisotropic media

Abstract

The electromagnetic fields produced by an electric dipole immersed in an aniso tropic medium are considered. Various approaches to the problem are outlined with special reference to a cold plasma. An attempt is made to show the close relationship between previously published work on this subject. It is shown that information on the radiation field in an anisotrop ic media may be obtained directly from the shape of the refractive index surface.
