Tunable Terahertz plasmonic lens with external magnetic field

Abstract

A tunable Terahertz (THz) plasmonic lens based on a micro-slit structure is proposed. The micro-slit structure is designed with InSb materials, the dielectric property of which in the THz frequency regime functions similar to metals in the optical frequency regime, and can be altered by an external magnetic field. Thus, for this micro-slit structure, the… (More)
