Based on the expansion of a Gaussian beam in terms of spheroidal vector wave functions given by us and the generalized Lorenz–Mie theory that provides the general framework, a theoretical procedure to determine the scattered fields of a spheroidal particle for incidence of a Gaussian beam described by a localized beam model is presented. As a result, for a dielectric and conducting spheroidal particle, numerical results of the normalized differential scattering cross section are evaluated, and the scattering characteristics are discussed concisely.
