摘要：

In order to develop the compact high-power terahertz (THz) source, a 0.22 THz source is designed theoretically by adopting the structure of surface-wave oscillator (SWO). We focus on the influence of the slow-wave structure (SWS) on resonant frequency and optimization of the SWS. Combined with the choose of diode, the particle-in-cell (PIC) simulation is performed for the source. The results show that the optimum structure can work stably and generate a terahertz signal in the condition of a input voltage of 200 kV, a current of 2900 A, and a guiding magnetic field of 5 T. The resonant frequency of the output signal is about 0.22 THz, and the output power reaches 19.5 MW with its efficiency of about 3.3%.
