Influence of Interaction Retardation and Radiation Reaction on the Fano Resonance Efficiency in the System of Nanoparticles

详细

The system of metallic nanospheroids in the field of monochromatic light wave under conditions of manifestation of the Fano resonance is considered. The dimensions of the nanospheroids are much smaller than the wavelength of the incident radiation, but distances between them can be arbitrary. An analysis is made of the influence of the interparticle interaction and the reaction field on the inhomogeneity of the energy distribution of the collective oscillations of electrons in the system (the Fano resonance efficiency). It is shown that both the retardation and the reaction field contribute to an increase in the resonance efficiency.
