title: Scattering of on-axis Gaussian beam by a chiral spheroid.
abstract: Within the generalized Lorenz-Mie theory framework, an analytic solution to the scattering of an on-axis Gaussian beam by a chiral spheroid is presented by expanding the incident Gaussian beam, scattered fields as well as internal fields in terms of appropriate spheroidal vector wave functions. The unknown expansion coefficients are determined by a system of linear equations derived from the boundary conditions. Numerical results of the normalized differential scattering cross section are shown, and the scattering characteristics are discussed concisely.
