Abstract


The results of experimental and theoretical studies of specular
reflection suppression in diffraction of HCN-laser terahertz
radiation on InSb grating under surface plasmon-polariton
resonance condition are presented. Dependence of the
resonance position and its width is investigated vs. grating depth.
The dielectric film deposited on the grating surface is shown
to increase the resonance width and shift its maximum away
from the Rayleigh point. The resonance diffraction theory
presented agrees well with the experimental results, thus allowing
to investigate the influence of problem parameters on the
resonance characteristics.
