Oblique incidence reflectometry and spectroscopic ellipsometry of split-ring resonators in infrared

Ellipsometry and infrared polarized reflection spectroscopy at oblique incidence of golden split-ring resonators were simulated and discussed. The ellipsometric spectra were related to the reflection spectra for the two polarization of the incident wave, and with electric field being normal and para...

Description
Summary:Ellipsometry and infrared polarized reflection spectroscopy at oblique incidence of golden split-ring resonators were simulated and discussed. The ellipsometric spectra were related to the reflection spectra for the two polarization of the incident wave, and with electric field being normal and parallel to the plane of incidence, respectively. Near-field and bulk current distribution at the resonances proved that they correspond to the multiple plasmonic modes of the split-ring resonators. The calculated magnetic moment showed that at oblique incidence both magnetic and electric field induce the magnetic resonances.
