Dielectric ground plane design over bianisotropic media

Abstract

In this contribution we show how it is possible to construct a new multilayer dielectric ground plane using bianisotropic media that is highly reflective over a broad range of wavelengths at all angles. This omnidirectional dielectric reflector-unlike metal-is nearly totally lossless and can be engineered to have extremely high reflectivity. The plane wave solution is then used to study in a rigorous way the wave equations satisfied by the electromagnetic field in a layered structure filled with such a material. Numerical results are also presented as a function of the material parameters in order to demonstrate the features of this approach.
