Scattering and Absorption by Wavelength Size Discs

Abstract

An integral equation for the current density induced in flat lossy dielectric discs by incident polarized waves is solved by a partly analytic, partly numerical method designed specifically to be efficient for the disc shape with thickness small and radius comparable to the incident wavelength. The computed currents are then used to compute, for arbitrary direction and polarization of the incident wave, the bistatic scattering matrix elements, total scattering and absorption cross-sections. The extinction cross-section is found both by summing the latter two cross-sections and by using the optical theorem relating forward scatter and extinction.
