Electromagnetic scattering from irregularly shaped dielectric particles using vector Green's theorem
Abstract
Scattering of electromagnetic radiation from an irregular dielectric particle whose dimensions are comparable to the incident wavelength is solved as a classical boundary value problem in which the vector Green's theorem is used as a generalized boundary condition. The inscribed sphere, the particle surface, and the circumscribed sphere divide space into four regions. Vector spherical harmonic expansions are used outside the circumscribed sphere and inside the inscribed sphere; any convenient complete set of functions can be used in the regions in between. The resulting vector equations are reduced to a set of 41(1+2) linear equations where l is the maximum order of the spherical multipoles needed to describe the scattered field.
