摘要：
We report on the electromagnetic interactions between a two-dimensional periodic arrangement of resonant gold nanoparticles and a flat gold metallic film. We observe multi-peaks in the extinction spectra attributed to resonant modes of the hybrid system, resulting from the coupling between the Localized Plasmon of the nanoparticles with the underlying Surface Plasmon Mode. Simulations based on the Fourier modal method give good agreement with the experimental measurements and allow for the identification of the respective contributions.
