Influence of Non-Local Effect on the Scattering Properties of NonSpherical Plasmonic Nanoparticles on a Substrate

Аннотация

Based on the discrete sources method (DSM), a new mathematical model is constructed and implemented making it possible to take into account the nonlocal effect (NE) in problems of light scattering by plasmonic nanoparticles located on a substrate. The effect of allowing the NE on the integral scattering characteristics in the spectral range near plasmon resonance (PR) is investigated. It is shown that taking the NE into account leads to a shift and a significant change in the PR’s amplitude.
