Non-local effect influence on the scattering properties of non-spherical plasmonic nanoparticles on a substrate

Based on the Discrete Sources Method, a new mathematical model allowing to take into account the Non-locality Effect (NE) in problems of light scattering by plasmon nanoparticles located at a plane substrate has been constructed and realized. The effect of accounting for the NE on the integral scattering characteristics in the spectral domain, near the plasmon resonance (PR), was investigated. It has been shown that taking into account the NE leads to the shift and significant change in the amplitude of the PR.
