Eigenfunction solution of the scattering of beam radiation fields by spherical objects*

Abstract

The theoretical analysis of the scattering of a beam by a spherical object centered on the propagation axis is treated exactly. For both conducting and dielectric bodies, those cases of sphere radii smaller than, equal to, and larger than that of the beam are analyzed numerically and the power radiated in the far zone is obtained. The difference between the scattering of a beam wave and that of a plane wave is discussed.
