| 摘 要： | 针对0.14 THz大气窗口，利用CST微波工作室和3维粒子模拟软件，对共焦波导结构的太赫兹回旋行波管进行了冷腔色散和注波互作用的模拟研究。以TE06模式作为互作用工作模式，在电压为35 kV、电流为2 A、横纵速度比为0.85的电子束参数下，当输入信号为1 W时，得到最高2 kW的微波功率输出，3 dB带宽为3.5 GHz,增益为30 dB。

| Abstract: | The dispersion characteristics and beam-wave interaction simulation results for a 140 GHz confocal gyro-travelling wave tube are presented with the help of CST Microwave Studio and 3D PIC software. The TE06 mode of a confocal waveguide is chosen as the operating mode. At a voltage of 35 kV, current of 2 A, and horizontal to vertical velocity ratio of 0.85, a 3 dB bandwidth of over 3.5 GHz is achieved in simulation, along with the peak output power of 2 kW and the peak saturated gain of over 30 dB, when the input power is about 1 W. |
