Abstract：The analytical solution of spherical vector wave functions of electromagnetic fields in s-concentric homogeneous plasma anisotropic spheres is expanded in this paper. Applying the continuous boundary conditions of electromagnetic fields in (s-1) plasma anisotropic spherical shell’s surfaces, the unknown expansion coefficients in homogeneous s-concentric spheres and the scattering field in free space by a plane wave are derived. The numerical results are consistent by the presented method and Method of Moments (MOM) speeded up with the Conjugate-Gradient Fast-Fourier-Transform (CG-FFT) approach. A three-layer concentric plasma anisotropic spheres (the three permittivity tensors are similar) is calculated also, which conforms with the published results of the homogeneous plasma sphere. The findings presented in this paper may be applied in manufacture of new antenna, satellite communication, and other related areas.
