Va. Osipov et Mi. Ryazanov, EMISSION OF A CHARGE MOVING UNIFORMLY PARALLEL TO THE SURFACE OF A NONSTATIONARY MEDIUM, Laser physics, 8(5), 1998, pp. 1007-1012
Emission of a charge moving uniformly parallel to a plane surface of a
nonstationary medium is considered. The distribution of the energy of
emitted radiation in frequencies and directions is obtained for an ar
bitrary time dependence of parameters of a medium. The properties of s
uch an emission for slowly varying media are discussed, and the optima
l conditions for the observation of this emission are determined.
