Cerenkov Radiation and Electromagnetic Pulse Produced by Electron Beams Traversing a Finite Path in Air

摘要

Coherent Cerenkov radiation has been investigated previously in the time domain for an infinite path. The present calculations for a finite path length show an effect analogous to diffraction (in the frequency domain) in which radiation fields appear both at Cerenkov angles and at other angles. The latter have previously been named electromagnetic pulse fields. Keywords: Radiation Radio Frequency Emissions; Relativistic Electron Beams; Electrons in Air.
