Abstract :
The triode with virtual cathode (VC) generates gigawatt pulses in wide frequency band. Basically, existing theoretical investigations of this system were carried out by method of numerical simulations and did not explain many experimental facts. The analytical description is more successful for investigation of generation mechanism. Two theoretical models describing the generation mechanism of the electromagnetic oscillation radiation in the virtual cathode triode are presented in this paper
