SPECTRAL-DOMAIN DYADIC GREEN-FUNCTION IN LAYERED CHIRAL MEDIA

A spectral-domain dyadic Green's function formulation defining the fields in a multilayer chiral medium resulting from the arbitrary distribution of sources is presented. The constitutive parameters and the chirality of each layer are assumed to be different. The fields are obtained in terms of electric- and magnetic-type dyadic Green's functions. The singular behavior of these dyadic Green's functions in the source region is taken into account by extracting the delta function singularities. The fields in any layer are obtained in terms of the appropriately defined global reflection and transmission matrices.
