Webradiant SP radiation has been observed from a so-called Smith-Purcell free-electron laser (SP-FEL) in which the electrons are bunched by the lasing process. As in other slow-wave structures, the electron beam in a SP-FEL interacts with an evanescent wave for which the phase velocity matches the electron velocity and ampliﬁes it. Webrespect, a THz source based on Smith-Purcell radiation (SPR) mechanism is promising, because SPR appearing when a charged particle moves above and parallel to a grating …
