RADIATION FROM A CHARGED PARTICLE MOVING THROUGH A PLATE

The results of calculation of the angular distribution of radiation emitted by a charged particle passing through an isotropic ferrodielectric plate and through a crystalline plate are presented. In the case of thick plates, the main contribution is due to the Vavilov--Cherenkov radiation. An investigation of the solution shows that in the frequency range in which the projections of the wave vector and the Poynting vector on the particle velocity have opposite signs, the Vavilov-- Cherenkov radiation ia emitted through the back wall of the plate. The radiation emitted by a charged particle moving through thin dielectric plates is also considered. (auth)
