Polarizability dyadics of small bianisotropic spheres

Abstract

The low-frequency scattering response of a homogeneous sphere made of a general linear bianisotropic material is quantified in terms of polarizability dyadics. The polarizability dyadics are then used to generalize the Maxwell-Garnet model for a composite obtained by randomly suspending small bianisotropic spheres in an isotropic achiral host medium
