Abstract

Transition radiation (TR) emitted by a charged particle incident obliquely on a perfectly conducting surface is considered. A method is proposed that allows one to calculate the characteristics of backward radiation at a finite distance, including in the so-called pre-wave zone. Particular cases of a flat target, as well as a target in the form of a cylindrical surface whose axis is perpendicular to the trajectory of the particle are considered. In the first case, the radiation characteristics in the wave zone, calculated by the model proposed, are in complete agreement with available results. In the second case, when a detector is situated in the pre-wave zone, the radiation is focused. The properties of radiation are discussed as a function of the shape of the target surface, the angle of incidence of a particle, and the distance to the detector.
