Paper Abstract

A modified double-interaction model is applied to the study of backscattering from metallic particles on conducting substrates. Polarization parallel or perpendicular to the plane of incidence is considered. The agreement with the experiment is successfully checked for metallic spheres of two different diameters and for a metallic cylinder on a flat conducting substrate. Using the model this enables a systematic study of some features of the backscattering patterns and, in particular, the angular positions of the minima, strongly dependent on the size. Some applications of this dependence are proposed, in particular, the possibility of distinguishing the size of the particle on the substrate and the distance from its center to the substrate.
