Abstract
Based on an extension of the discrete sources method (DSM) our newly developed computer model enables us to analyze polarised light scattering by 3D non-spherical particles accounting for non-local effects (NLE) for plasmonic nanoparticles. Using this theory, computer simulations for spheroid particles of different shape have been conducted. The influence of the NLE both considering the Hydrodynamical Drude model and the generalised non-local optical response on the spectral scattering properties has been analyzed. It has been found that there is a strong influence of particle shape and polarisation of the incident radiation on the scattering properties of a plasmonic particle. Additionally, it has been demonstrated that NLE for non-spherical 3D particles leads to a decrease in intensity of the corresponding localised surface plasmon resonance and provides a blue shift of the plasmon resonance for the non-spherical particles.
