Abstract

We analyzed semi-infinite reflection coefficients at an interface formed by a bi-anisotropic metamaterial (MM) slab and an air region by considering boundary effects. Corresponding expressions for reflection coefficients are derived using the ray-tracing technique. Derivations are validated by simulated S-parameters of a bi-anisotropic MM slab composed of circular split-ring-resonators. It is noted that while reflection coefficients at left and right interfaces of the analyzed bi-anisotropic MM slab are closely linked to one another aside from the resonance, they are different from one another especially around resonance.
