### Abstract

We investigate the far-field scattering of an eccentric sphere (a host sphere with an eccentric spherical inclusion) arbitrarily located in a shaped beam. The extended beam-shape coefficients of the incident beam of arbitrary direction and location in spherical coordinates are presented and evaluated by using the rotational addition theorems for spherical vector wave functions and the approach of the localized approximation. Based on the generalized Lorenz–Mie theory, a general infinite set of scattering equations of an eccentric sphere arbitrarily illuminated is given. The angular distribution of the scattered intensity is calculated and discussed with comparisons of scattered intensities with respect to different incidence angles, center–center separation distances, and refractive indices of the host and the inclusion.
