Scattering of Gaussian beam by a spherical particle with a spheroidal inclusion

A generalized Lorenz-Mie theory framework (GLMT) is applied to the study of Gaussian beam scattering by a spherical particle with an embedded spheroid at the center. By virtue of a transformation between the spherical and spheroidal vector wave functions, a theoretical procedure is developed to deal with the boundary conditions. Numerical results of the normalized differential scattering cross section are presented.

Research highlights► Exact analytic solutions are presented for computing Gaussian beam scattering. ► This study extends to a spherical particle with an embedded spheroid at the center. ► The scattering characteristics are more different compared to a two-layered sphere.
