摘　　要：在无源各向异性铁氧体和等离子体介质的球矢量波函数基础上,利用第一、二类球Bessel满足相同的微分方程和递推关系,给出了各向异性铁氧体球涂覆均匀等离子介质对平面波散射的理论公式,并给出数值计算的结果,预计本文结果可应用于微波器件以及目标特性等领域。Based on the spherical vector wave functions in source-free anisotropic plasma and ferrite medium and the first,second spherical Bessel functions satisfying the same differential equation and recursive formula,the electromagnetic fields in terms of spherical vector wave functions in anisotropic ferrite sphere coated anisotropic plasma media are obtained,and then the numerical results of EM scattering by two concentric anisotropic spheres are given.The results presented here can be used in the microwave devices and characterization of target.
