Abstract

We consider Vavilov-Cherenkov radiation occurring as a result of uniform motion of a point charge in vacuum near a finite-size prismatic target with an arbitrary permittivity. The expression derived for the spectral-angular density of radiation contains a center of emission of Vavilov-Cherenkov radiation, which depends on the angle of flight of the point charge relative to the target. The results indicate that the main contribution to the formation of Vavilov-Cherenkov radiation comes from the polarization current occurring at the interface between the media.
