Abstract

We propose a retrieval procedure for extraction of electromagnetic properties of bianisotropic metamaterial (MM) slabs involving no sign-ambiguity. Toward this end, as different from the studies in the literature, we derive a closed-form expression for the intermediate variableT(propagation factor) and use it to obtain sign-ambiguity-free electromagnetic properties of bianisotropic MM slabs. We utilized 3D CST Microwave Studio to simulate scattering parameters of a bianisotropic MM slab composed of circular split-ring-resonators and to validate the derived closed-form expressions. The effects of substrate loss, geometrical parameters, and noise in S-parameters were examined to assess the capability of the proposed method.
