A plane wave scattering from two concentric ferrite anisotropic spherical shells

Electromagnetic fields in homogeneous ferrite anisotropic medium can be expressed as the addition of the first and second spherical vector wave functions in ferrite anisotropic medium. Applying the boundary conditions of electromagnetic fields in the interface of two concentric ferrite anisotropic spherical shells´ medium, the expansion coefficients of electromagnetic fields in terms of spherical vector wave functions in ferrite anisotropic medium and free space can be derived, and then the radar cross sections (RCSs) of a plane wave scattering by two concentric ferrite anisotropic spherical shells can be obtained. Some numerical results are given in this paper.
