Abstract-3D quasioptical theory of terahertz superradiance of an extended electron bunch moving over a corrugated surface
http://prl.aps.org/accepted/8b07fYcaNd414e30a8d77a25ef1688040713983d1 N. S. Ginzburg, A. M. Malkin, A. S. Sergeev, I. V. Zotova, V. Yu. Zaslavsky, and I. V. Zheleznov We consider the superradiance of an extended relativistic electron bunch moving over a periodically corrugated surface for the generation of multi-megawatt terahertz pulses. To study the above process we have developed a three-dimensional, self-consistent, quasi-optical 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.
