Abstract

We apply the boundary element method to the analysis of the plasmon response of systems that consist of coupled metallic nanoscatterers. For systems made of two or more objects, the response depends strongly on the individual particle behavior as well as on the separation distance and on the configuration of the particles relative to the illumination direction. By analyzing the behavior of these systems, we determine the smallest interaction distance at which the particles can be considered decoupled. We discriminate the two cases of particle systems consisting of scatterers with the same and different resonance wavelengths.
