Scattering of electromagnetic arbitrary-shaped beams by particles is a topic of growing theoretical (and practical) interest. This topic, however, has suffered from a lack of description of shaped beams that exactly satisfies Maxwell’s equations. As a remedy, this paper presents an exact description of arbitrary-shaped beams for use in light-scattering theories. This general description is illustrated by consideration of Gaussian beams in the so-called modified localized approximation.
