Green's Functions for an Anisotropic Medium. Part 2. Two-Layer Case

摘要

The Dyadic Green's Functions (DGF) of a two-layer biaxially anisotropic mediumare derived. The principal coordinate system of the anisotropic medium is allowed to have arbitrary orientation with respect to the layer geometry. The formulation is based on the unbounded Dyadic Green's Function derived in Part I of the sequel. Using the matrix method, the coefficients of the two-layer DGF are expressed in terms of half-space Fresnel reflection and transmission coefficients. To complete this procedure, the various relevant half-space Fresnel coefficients are derived. The form in which the results are presented has a physically meaningful and compact structure. A numerical example is provided where we have computed the reflectivities. Green's functions, Electromagnetic waves, Anisotropic medium, Layered medium.
