### Abstract

An analytic solution to the scattering by an infinite chiral cylinder, for oblique incidence of an on-axis Gaussian beam, is constructed by expanding the incident Gaussian beam scattered fields as well as internal fields in terms of appropriate cylindrical vector wave functions. The unknown expansion coefficients are determined by a system of linear equations derived from the boundary conditions. For a localized beam model, the scattering characteristics that are different from the case of an infinite dielectric cylinder are described in detail and discussed concisely.
