Microellipsometry study of plasmonic properties of metal-insulator-metal structures with ordered lattices of nanoparticles

Microellipsometric investigations of metal-insulator-metal (MIM) structures with regular square lattices of nanocylinders as one metallic layer are presented together with a theoretical description of all dipolar interactions in such a system. A comparison between the theoretical and experimental results is made, which clearly demonstrates the influence of surface plasmon on the optical properties of such MIM systems. The hybridization of localized and surface plasmon modes is revealed.
