Abstract
The diffraction of a plane wave at the corrugated boundary of vaccum and a negative-velocity material was discussed. The transformation of the refracting medium from negative (positive) phase velocity type was found to have an influence over diffraction efficiencies. It was found that most of the nonspecular components were like evanscent plane waves as they were characterized by Re(βn(1)=0. The diffraction efficiencies were affected by transformation of refracting medium from negative-phase-velocity to positive-phase-velocity. The effect on the diffraction efficiencies were found to have increased with the increase in corrugations depth.
