Matrix approach for light scattering from a multilayered rotationally symmetric bianisotropic sphere

Abstract

Electromagnetic wave propagation in rotationally symmetric bianisotropic structures is investigated. Spherical solutions are presented in compact tensor matrix form with separated angle and radial variables. The separation is achieved by applying tensor functions F based on ordinary scalar and vector spherical harmonics. Such tensor functions describe the angle dependences of partial spherical waves. The scattering problem for a multilayered bianisotropic spherical particle is solved using an impedance tensor and evolution operator transfer matrix . These quantities have been previously defined for planar and cylindrical structures. The approach developed is applied to computing the differential cross section of a plane wave from a two-layer bianisotropic sphere.
