Description
In the first part of the talk I will briefly review the literature on Smith–Purcell Free Electron Lasers, and speculate about the possibility of scaling down a radio wave amplifier: coupled-cavity Travelling Wave Tube, to obtain a light-generating device based on nanostructures. In the second part of the talk I will show concrete numerical results on Cherenkov Diffraction Radiation: the Fabry–Perot effect for the evanescent wave, and the anti-reflection layer for the evanescent wave.
