摘要：

Scattering of a plane wave by a plasma anisotropic spherical shell is considered in this paper and scattered fields are obtained in spherical coordinates. The electromagnetic fields in a plasma medium and in a free space are expanded in terms of the spherical vector wave functions (SVWFs) for a plasma anisotropic medium and the SVWFs in an isotropic medium. Numerical results for very general properties of the plasma dielectric material spherical shells are given. And those results obtained in a special case using the present method and the method integrating the method of moments (MoM) the conjugate-gradient fast-fourier-transform (CG-FFT) approach are compared, and a very good agreement is found. The results presented here can be used in the antenna design, satellite communications channel design and characterization, and target shielding studies.
