摘要
回旋返波管作为一种频率可调谐的大功率太赫兹辐射源器件,具有较好的实用前景。本文根据回旋返波管线性理论设计了一只中心工作频率在0.22THz的准光波导回旋返波管,采用自主研发的三维粒子模拟软件CHIPIC对其进行数值模拟研究,分析其工作特性。仿真结果表明:所设计的回旋返波管可获得14kW的峰值功率输出,输出功率大于5kW时调谐带宽大于1GHz。
Gyro-Backward wave oscillator （Gyro-BWO） has great practical prospects as a frequency tunable high-power terahertz radiation source device. According to the Gyro-BWO linear theory, the arti-cle designs an operating frequency of 220 GHz quasi-optical waveguide Gyro-BWO. By using independent research and development of three-dimensional particle simulation software CHIPIC, its operating charac-teristics are numerically simulated and analyzed. Simulation result shows that the Gyro-BWO can obtain 14kW power output. As output power great than 5 kW, the tuning bandwidth is over 1 GHz.
