Plane-wave diffraction at the periodically corrugated boundary of vacuum and a negative-phase-velocity material
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 no...
