Paper Abstract

In this paper, exact analytical forms of the normal surface and eigenpolarizations in anisotropic media are obtained. Both the permitivity and permeability tensors are supposed to be anisotropic, becoming simultaneously diagonal in the principal system of coordinates. The equation of normal surface in various forms and exact relations for eiggenpolarizations are presented and their properties are discussed. Orthogonality relationships between the eigenmodes are also introduced. Sufficient conditions for existence of two, one, or no optical axes are thoroughly established. The analysis is extended for the case of electrically or magnetically optically active materials, and exact form of eiggenpolarizations are derived. It is shown that for the medium with no optical axes, being referred to as pseudo-isotropic medium, under certain conditions there is exactly no reflection. This phenomenon is totally independent of the polarization, angle of incidence, and even wavelength.
