Inverse Smith-Purcell effect near rough surfaces

  title={Inverse Smith-Purcell effect near rough surfaces},
  author={Zh.S.Gevorkian and V.Gasparian},
Absorption of a photon by an electron moving parallel to a rough surface is studied. In the weak scattering regime we have evaluated the absorption probability of absorption of a single photon of energy ω. It is shown the absorption probability with diffusional contribution becomes large by a lin/l ≫ 1 factor compared to the analogous result with the single scattering contribution. The maximum of probability takes place for the infrared wavelengths and strongly depends on the particle energy…

Theoretical Analysis on Smith-Purcell Free-Electron Laser

The first observation of radiation emitted by an electron passing over a diffraction grating was made long ago by Smith and Purcell [Smith, S. J.], and the idea of using this effect in a
