Abstract

Surface-phonon polaritons on a 1D SiC grating are studied by directional absorptivity measurement at 10.6 micrometers and variable angle reflectometry between 8 and 14 micrometers . Using a volume integral approach, numerical simulations of the electromagnetic scattering problem are carried out. The calculated reflectance spectra are in good agreement with the experimental observations.
