As it was noted before, the transition radiation is a manifestation of so-called "polarization mechanism of radiation", in which the field of a charged particle passing through the medium deforms (polarizes) the electron shells of the medium atoms. It is the dynamic polarization of the medium...
In particular, for a given observation direction two wavelengths are emitted instead of one wavelength of the standard Smith-Purcell effect. For a rough surface we show that the main contribution to the radiation intensity is given by surface polaritons induced on the interface between two media. ...
