Investigation of diffraction of optical range electromagnetic waves on dielectric nanovibrator

The antenna under investigation is nanocrystal, covered with a metal film. Complex dielectric permeability of metals in an optical range is considered. The decision of a boundary problem was reduced to the solving integrodifferentianal equations concerning intensity of electric field in the vibrator. The method of solving of this equation, which combines Galerkin method and collocation method is developed. Electrodynamic characteristics of antennas-nanocrystals are investigated.
