Dyadic Greenu27s Functions for Multi-Layered Uniaxially Anisotropic Media with Arbitrarily Oriented Optic Axes

摘要

Dyadic Greenu27s functions (DGFs) for multi-layered uniaxially anisotropic media are developed analytically when the optic axis of each layer is arbitrarily oriented. DGFs are expressed in terms of two characteristic waves – ordinary and extraordinary, in the k-domain with Fresnel reflection and transmission coefficients. The Fresnel coefficients are obtained by the application of boundary conditions at the anisotropic interfaces. The results have been checked in the limiting cases with existing results analytically. The results of this work can be used in electromagnetic radiation and scattering problems in the presence of multi-layered anisotropic media.
