Spectra of Cherenkov and transition radiation excited by a train of electron bunches in dielectric structures of rectangular cross-section
The peculiarities of radiation spectra of a single relativistic electron bunch or train of bunches in an infinite rectangular
 dielectric waveguide, in a semi-infinite dielectric waveguide, and in a dielectric waveguide of finite length
 were theoretically explored. Single-mode and m...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | The peculiarities of radiation spectra of a single relativistic electron bunch or train of bunches in an infinite rectangular
dielectric waveguide, in a semi-infinite dielectric waveguide, and in a dielectric waveguide of finite length
were theoretically explored. Single-mode and multimode modes were surveyed. In the first case, the excited fields
corresponding to Cherenkov and transition radiation were identified. In the second case, the substantial growth of
field amplitude was obtained due to interference of many excited transversal modes. Limitation on maximum field
amplitude and amount of contributing bunches caused by the fields removal with a group velocity was found. The
features of excited spectra caused by a regular sequence of bunches were investigated. Selective excitation of
transversal modes and corresponding field waveform were considered for the arbitrary rectangular geometry.
