Analytical Method and Semianalytical Method for Analysis of Scattering by Anisotropic Sphere : A Review

Abstract EN

The history of methods for the electromagnetic scattering by an anisotropic sphere has been reviewed.

Two main methods, angular expansion method and T-matrix method, which are widely used for the anisotropic sphere, are expressed in Cartesian coordinate firstly.

The comparison of those and the further exploration on the scattering field are illustrated afterwards.

Based on the most general form concluded by variable separation method, the coupled electric field and magnetic field of radial anisotropic sphere can be derived.

By simplifying the condition, simpler case of uniaxial anisotropic media is expressed with confirmed coefficients for the internal and external field.

Details of significant phenomenon are presented.
