Abstract

This paper focuses on the effective properties of bi-anisotropic mixtures. The effective material parameters of mixtures are derived which consist of spherical, arbitrarily bianisotropic inclusions in an isotropic host medium. The parameters of the inclusions can have the full range of 36 components of a general linear electromagnetic medium. Six-vector notation is used to derive the results, but the final expressions are also presented in a form of separate dyadic components. The inclusions are allowed to have an arbitrary orientation distribution. The special cases of aligned and random orientations are given special emphasis. Numerical examples are calculated for two mixtures where inclusions are made of either aligned chiral or omega spheres
