Terahertz surface plasmon interaction on a corrugated metal surface

摘要

We present a study of terahertz surface plasmon excitation and propagation on a periodical metallic surface (grating), which includes the development of: 1) grating couplers, 2) curved groove gratings for surface plasmon focusing, 3) Bragg gratings for retro- and non-collinear reflection of surface plasmon.
