Abstract

We have studied optical plasmonic properties of metal surfaces with a periodic lattice of voids buried in metal just beneath the surface. We have calculated reflection spectra of such surfaces in the framework of a self-consistent electromagnetic multiple-scattering layer-KKR approach. We investigated two types of plasmon excitations: surface plasmon-polaritons propagating at the planar surface of metal and Mie plasmons localized in voids. The coupling between these two types of plasma oscillations can be modified by tuning the structure parameters (e.g., void diameter and/or the period of the void lattice) or by changing the angle of incidence of incoming light.
