Propagation in bianisotropic media - reflection and transmission
Author
Summary, in English
In this paper a systematic analysis that solves the wave propagation problem
in a general bianisotropic, stratified media is presented. The method utilizes
the concept of propagators, and the representation of these operators is simpli-
fied by introducing the Cayley-Hamilton theorem. The propagators propagate
the total tangential electric and magnetic fields in the slab and only outside
the slab the up/down-going parts of the fields need to be identified. This
procedure makes the physical interpretation of the theory intuitive. The re-
flection and the transmission dyadics for a general bianisotropic medium with
an isotropic (vacuum) half space on both sides of the slab are presented in a
coordinate-independent dyadic notation, as well as the reflection dyadic for
a bianisotropic slab with perfectly electric backing (PEC). In the latter case
the current on the metal backing is also given. Some numerical computations
that illustrate the algorithm are presented.
