MULTISCATTERING EFFECTS IN THE FAR-FIELD REGION FOR 2 SMALL PARTICLESON A FLAT CONDUCTING SUBSTRATE

The scattered field in the far-field region for two small metallic par ticles on a conducting substrate is analysed as a function of both the ir separation and the angle of incidence. Special attention is paid to multiple scattering, which appears when the particles are very close, as well as to its related effects such as its influence on the enhanc ed backscattering phenomenon and depolarization of the incident beam i n the plane of incidence.
