Light scattering of an arbitrarily oriented cubic particle within the Wentzel–Kramers–Brillouin approach

Abstract

The Wentzel–Kramers–Brillouin approximation is applied to study the light scattering properties of an arbitrarily oriented cubic particle. The form factor and extinction coefficient of this particle are expressed in simple analytical expressions. The effects of certain physical parameters, namely angles of incidence, scattering azimuthal and zenith angles, refractive index and size parameter, on the form factor and extinction coefficient are analyzed. Some numerical examples are also presented to illustrate the results.
