Abstract

The property of nonreciprocity in electromagnetic structures is a pivotal feature when designing useful devices such as directional phase shifters, circulators, isolators, and gyrators. The performance of these components is judged by the nonreciprocity index, indicating the degree of nonreciprocity. In this work, we consider a slab filled with a homogeneous anisotropic medium with an arbitrary and full permittivity matrix. The scattering parameters of the formulated four-port network are analytically evaluated and a nonreciprocity index is defined. The variations of this function with respect to the complex elements of the effective permittivity matrix are shown and general conclusions are drawn.
