Analyzing the scattering of light by a cluster of nanoparticles in thin metal film with discrete sources method

Based on the Discrete Sources Method mathematical model of an optical antenna has been considered and realized. The considered antenna consisted of a nanoparticles cluster located inside a thin metal film which was disposed on a glass substrate. Scattered intensity obtained via computer modeling is presented, including the case of evanescent waves. It has been established that by varying the cluster geometry the scattered light could be concentrated in a wide range of directions.
