Plane-wave diffraction at the periodically corrugated boundary of vacuum and a negative-phase-velocity material

Mostrar todas las versiones(2)

Considering the diffraction of a plane wave by a periodically corrugated half-space, we show that the transformation of the refracting medium from positive (negative) phase velocity to negative (positive) phase velocity type has an influence on the diffraction efficiencies. This effect increases wit...
