We consider the superradiance of an extended relativistic electron bunch moving over a periodically corrugated surface for the generation of multimegawatt terahertz pulses. To study the above process we have developed a three-dimensional, self-consistent, quasioptical theory of Cherenkov stimulated emission which includes a description of the formation of an evanescent wave over a corrugated surface and its excitation by rf current induced in the electron bunch.
我们考虑了在周期性波纹表面上运动的扩展相对论电子束的超辐射，以产生兆瓦级太赫兹脉冲。为了研究上述过程，我们开发了一种三维、自洽、准光的切伦科夫受激辐射理论，其中包括对在波纹表面上形成的消逝波及其由电子束中感应的射频电流激发的描述。
