Research output: Contribution to journalConference articlepeer-review


We analyze the diffraction of a plane wave by a diffraction (surface-relief) grating made of an Isotropic negative phase-velocity material. Three different approaches are employed, and the results are compared with those for conventional (i.e., positive phase-velocity) materials. Resonant excitation of surface waves on the new types of gratings is examined.
