Time- and Frequency-Domain Study for Electron Beams Penetrating Dielectric Nanospheres: Fingerprints of Cherenkov and Transition Radiation

Abstract We present a theoretical study of Cherenkov and transition radiation for swift electron beams penetrating dielectric nanospheres using material models of different sophistication. Specifically, we perform a combined time-domain (numerically, via the discontinuous Galerki...
