Abstract
The long-wavelength transition radiation from the ultrarelativistic bunched elect rons on the thin metallic transverse-limited target has been considered. We have investigated the properties of transition radiation and whole electromagnetic energy flux in a pre-wave zone. The general formula for spectral-angular density of electromagnetic energy flux through the small-size detector in the forward and backward direction is obtained and analysed. We have showed that the angular distribution of electromagnetic energy flux in the prewave zone is strongly distorted in comparison to the case of transverse-unlimited detector.
