- Аннотация: The problem of excitation of a core-shell particle located on a transparent substrate by a fieldof an evanescent electromagnetic wave is considered. The particle consists of a dielectric core with a metal nanoplasmonic shell in which spatial dispersion occurs. Based on the Discrete Sources Method, a model has been constructed that considers the influence of the presence of the substrate and nonlocality in a metal on the optical scattering characteristics. The effect of the asymmetry of the particle geometry on the optical characteristics of the near field has been investigated. It was found that the asymmetry of the particle geometry significantly affects the intensity enhancement coefficient, as well as the absorption cross-section.
