Numerical and experimental study of controlling characteristics of generation in low-voltage vircator by external harmonical signal

In the work we display the experimental and computational investigation of dynamics of an electron beam with virtual cathode in diode space with breaking voltage. Controlling of system dynamics with the help of microwave velocity modulation of the electron beam is discussed. Different complex regimes depending on the value of breaking voltage and the parameters of controlling signal, and defining the system behavior are observed and analyzed.
