Transition radiation and surface-plasmon generation by an electron beam
  
Transition radiation and surface-plasmon generation by en electron normally impinging on a planar surface. This radiation was predicted by Ginzburg and Frank in 1946. See details of the theory and references in F. J. García de Abajo, Rev. Mod. Phys. 82, 209 (2010).
