Dyadic Green's functions for two-layered electrically gyrotropic media

Abstract

Dyadic Green's functions (DGFs) for a two-layered electrically gyrotropic or gyroelectric medium are derived using k-domain approach. Gyroelectric medium is assumed to be bounded by isotropic media in the upper and lower sides. Transmission and reflection coefficients for the two-layered medium used in the DGFs are expressed in terms of half space transmission and reflection coefficients using the matrix method with the application of boundary conditions. This drastically reduced the complexity of the problem for the two-layered structure. The results presented here can be used for radiation or scattering problems in the presence of a layered media involving complex medium such as gyroelectric.
