A relativistic surface wave oscillator based on overmoded structure is simulated with particle-in-cell method. The output signal is generated with a frequency of 0.148 THz and the main output mode of TM01 according to numerical results. The electromagnetic field may leak into diode region because the device is lack of effective reflector. The characteristics of this device and the influence of the parameters of diode on the device are studied via particle simulation. The simulation results indicate that the electromagnetic field leaking to diode region has little impact on the work status of the device but the output power is affected by the structure of diode seriously.
