Mechanism of microwave generation by virtual cathode oscillation

A simple model is developed to describe the virtual cathode oscillation. With this model, it is found that the frequency dependence of the microwave power gain is determined by the phase relation between the oscillating electric field and the modulated electron beam current. Analytical expressions are given for the frequency dependence of the gain and for estimation of the maximum efficiency of microwave energy extraction from the electron beam.
