Abstract

By the present time the photon crystals on the basis of metal-dielectric structures have been investigated in more detail in the IR, where they have doubtless technological advantages and based on such crystals structures both with conventional and unconventional photon band gap characteristics can be realised. At the same time, as it was noted in [1], the structures of metallic nanoparticles can be of interest in spectral range close to the frequency of a small particle surface plasmon. For the majority of metals that is the UV or the visible. It is known that absorption and scattering by metallic nanoparticles is resonantly enhanced over the plasmon frequency region and surface plasmon characteristics are extremely dependent on particles sizes, shapes and concentration.
