摘要

Free electrons passing along the surface of the grating produce a stimulated emission, referred to as the Smith-Purcell (SP) effect. Here we firstly report theoretically evidence of the inverse Smith-Purcell effect at about 300GHz (ISP) by loading the specially designed photonic crystals (PCs) with negative refractive on a slits structure, which could provide a new idea for coherent Smith-Purcell. The inverse Smith-Purcell effect reflect that with the observation moving from the front to the rear, the observation frequency change first from the intermediate frequency to the high frequency, and then from the low frequency to the intermediate frequency, which is different from the normal SP. The proposed ISP is of great significance for obtaining power enhanced, coherent and tunable terahertz radiation.
