THz Diffraction Radiation Analysis of Finite Graphene Strip Grating with Grounded Dielectric Substrate Excited by Electron Beam

Abstract: We consider THz range diffraction radiation (DR) of a harmonically modulated electron beam passing above graphene-strip grating on dielectric substrate with perfectly electric conducting ...
