Related Plasmon Oscillations in a Cluster of Two Silver Nanocylinders of Different Diameter

Abstract

A two-dimensional problem of the diffraction of a plane wave of the light range on a cluster consisting of two self-similar, silver nanocylinders of different diameter is considered. The frequency characteristics of the scattering diameter, the spatial distribution of the field components, and the scatterplot are calculated by strict numerical methods. The influence of the angle of incidence, the cylinder distance, the coefficient of self-similarity and silver loss on the spectra of the scattering diameter, and the scatterplot in the light wavelength range is studied. It is shown that the maximum value of the electric field component in the quasistatic region at the output of such a system cannot be more than ten times the values of the incident field.
