Spectral Green's functions for multilayered bianisotropic media

We derive the spectral Green's function of a multilayered structure involving bianisotropic materials. Such materials offer new degrees of freedom to improve, besides, the radiation properties of multilayered structures. We propose an analytical study in the spectral domain of bianisotropic layers that are characterized in terms of transmission matrices leading to an equivalent circuit representation of the whole multilayered structure. Finally, a numerical result is presented for the special case of the chirostrip antenna consisting of a single chiral grounded slab.
