SPECTRAL DYADIC GREENS-FUNCTION FORMULATION FOR UNIAXIAL BIANISOTROPIC SUPERSTRATE SUBSTRATE STRUCTURE

In this paper, spectral-domain dyadic Green's functions for the rime harmonic electric current source embedded in a two-layer grounded uniaxial bianisotropic media are obtained using Fourier transform. It is shown that in the uniaxial bianisotropic medium, total spectral electromagnetic field can also be separated into the superposition of transverse electric (TE) and transverse magnetic (TM) wave. Because of the generality of constitutive relations our results include the special cases of achiral, uniaxial, reciprocal and nonreciprocal biisotropic media.
