Abstract: We propose to generate high-power electromagnetic pulses by using the phenomenon of Cherenkov superradiance (SR) of extended electron bunches that propagate in free space over a corrugated surface. Both an analysis performed in the framework of a quasi-optical approximation and a direct particle-in-cell simulation demonstrate the possibility of generating multimegawatt picosecond pulses of radiation in the terahertz range using the proposed mechanism.
