Excitation and Far field Spectroscopy of surface plasmons in Gold nanostructures
MetadataShow full item record
The properties of surface plasmons (SPs) and their excitation by a light wave are considered. The interaction of light with a metal nanostructure resulted in transmission, reflection and diffraction of light. The spectra of light obtained from these channels display excitation of SP modes at certain incidence angles and wavelengths. The interaction of SP modes near the normal incidence can result in energy and momentum spectral gaps and variations of the widths of SP resonances. The SP dispersion relations were described with the model of two coupled modes, and the spectral amplitude distribution of the transmitted and reflected light were simulated following Rayleigh approach.
