Abstract :
In a structure of nano-scale metal film with dielectric medium loading, the surface plasmon polaritons (SPPs) excited by a uniformly moving electron beam bunch can be transformed into Cherenkov radiation with intensity enhancement in the medium. Based on the mechanism, Surface Polariton Cherenkov Light Source (SPCLS) is proposed and explored.
