Representation of dyadic Green's functions for general anisotropic media

Abstract

A novel and practical method to obtain the complete set of the dyadic Green's functions for general anisotropic media is presented. The method is based on the k-domain representation of the fields in terms of wave matrices. The Fourier transformed Green's functions are obtained through inverses of wave matrices, which lead to the final form of the dyadic Green's functions. It is shown that the knowledge of the inverse of one type of wave matrix is sufficient to find the complete set of the dyadic Green's functions for a general anisotropic medium
