Abstract：
The dominant frequency in an inward-emitting coaxial virtual cathode oscillator is solved analytically based on the steady-state relativistic-fluid-Maxwell equations. Full three-dimensional numerical simulation with the PIC method is carried out using the TS3 module of the MAFIA code. The frequency spectrum and the output power are obtained by monitoring the five propagating modes in the cylindrical output waveguide. The result shows that when the anode reflector exists, the frequency spectrum can be improved effectively by the formed quasi-cavity and hence the corresponding energy conversion efficiency can be enhanced.
