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.
针对由相对电容率和相对磁导率均为单位 1 的磁电旋光材料制成的球体的电磁散射,构建了精确的转移矩阵。当球体的磁电旋光矢量与入射平面波的电场或磁场共线或反平行时,总散射效率和前向散射效率低于磁电旋光矢量与入射平面波的传播矢量平行时的情况。当传播矢量与磁电旋光矢量共线或反平行时,不存在后向散射。
