Contributions to the electromagnetic wave theory of bounded homogeneous anisotropic media.

Abstract

An electromagnetic wave theory of bounded homogeneous anisotropic media is developed by using the method of angular spectrum expansion. The series and integral representations of the circular cylindrical wave functions and the spherical wave functions of the first, second, third, and fourth kind for homogeneous anisotropic media are obtained. Each coefficient of the Fourier series of a circular cylindrical wave function is a one-dimensional finite range of integration and every coefficient of the spherical-harmonic-function series is a two-dimensional finite range of integration. The addition theorem of wave functions for anisotropic media can be derived from that of wave functions for isotropic media. Weyl's method of deriving the scalar Green's function in isotropic media is generalized to the study of the dyadic Green's function in anisotropic media. The cold homogeneous magnetoplasma is considered as an illustrative example. For a cold homogeneous magnetoplasma, simplified series representations of wave functions and dyadic Green's functions are given. The distributional singular behavior of the dyadic Green's functions in the source region is investigated and taken into account by solving the static problem and the boundary integral equation is derived.
