Light scattering by magnetoelectrically gyrotropic sphere with unit relative permittivity and relative permeability.

An exact transition matrix was formulated for electromagnetic scattering by a sphere made of a magnetoelectrically gyrotropic material with unit relative permittivity and relative permeability. The total scattering and forward scattering efficiencies are lower when the magnetoelectric gyrotropy vector of the sphere is either coparallel or antiparallel to the electric field or magnetic field of an incident plane wave than when the magnetoelectric gyrotropy vector is parallel to the propagation vector of the incident plane wave. Backscattering is absent when the propagation vector is either coparallel or antiparallel to the magnetoelectric gyrotropy vector.
