Abstract: A 0.22 THz continuously frequency-tunable gyrotron oscillator with quasi-optical resonator has been investigated in this paper. The operating frequency is changed by mechanically adjusting the mirror separation. The simulation results have demonstrated that an 11.7 GHz bandwidth of frequency tuning and output power of 38 kW could be achieved.
