Numerical Study of Dielectric Resonant Gratings

Abstract

In this chapter we have presented a review of plasmonic nanostructures investigations. A new design of optical antenna consisting of ZnO nanorod coated with a thin metal film is discussed. The solution of electromagnetic waves diffraction by a single metal-dielectic nanooscillator and two-dimensional uniform periodic grating of ones either located on the layered dielectric substrate was shown. Electrodynamic characteristics of one-and two-dimensional dielectric resonant gratings are considered in this chapter.
