摘　　要：以电子回旋脉塞非线性理论为基础,结合三维电磁仿真软件,通过导入高频场数值解替代理论解析的方法,对波瓣波导谐振腔高次谐波太赫兹回旋管进行了理论和模拟研究.给出了该类回旋管的起振电流、耦合系数以及注波互作用效率等重要参数,并在此基础上设计了一只工作频率为0.4 THz,工作模式TE_(33)模三次谐波波瓣波导谐振腔回旋管,其电子注参数为1.0 A,40.5 kV,横纵速度比1.5,互作用区引导磁场为5.09 T,输出功率达到3.3 kW.Based on the nonlinear self-consistent theory and the three-dimensional electromagnetic simulation software CST,the beam-wave interaction of gyrotron with irregular cross section is studied.Through importing high frequency fields which are the results of CST, the beam-wave interaction efficiency,coupling coefficient and starting current can be obtained.In addition,a 0.4 THz third harmonic TE33 mode gyrotron with a corrugated interaction cavity is presented according to this approach.The gyrotron with a 40.5 kV/l A electron beam,magnetic field of 5.09 T,and pitch factor of 1.5 can produce radiation with an output power of 3.3 kW.
