Abstract
The scattering of a cylindrical vector beam by a sphere is investigated within the framework of the generalized Lorenz-Mie theory (GLMT). The beam shape coefficients for cylindrical vector beams are calculated using an analytical expression obtained by integral localized approximation (ILA), and the scattering coefficients are expanded using Debye series (DSE). The beam shape coefficients are numerically evaluated and verified by comparing the reconstructed results with those obtained from the original fields. The far-field scattered intensities are numerically simulated, and the rainbows produced by the interaction of cylindrical vector beams and spherical particles are analyzed in detail.
