摘要 该文由功率-电压法和LC等效电路法的概念出发,利用电磁场软件ISFEL3D的后处理文件PAC3D中逐点提取的电磁场强度及其积分值,计算了同轴腔高阶TM_(310)模式与矩形波导基模耦合时,腔内漂移管中心的间隙阻抗,两种方法给出相同的计算结果。对于相同的模式,采用编程计算的结构参数模型可以得到较大的间隙阻抗实部。 Coupling of higher order transverse magnetic modes TM310 in microwave coaxial cavity of klystron with TE10 mode of rectangular waveguide is analyzed based on power-voltage and LC equivalent-circuit methods respectively. Gap impedances of output cavity were calculated by using of electromagnetic fields which was point-by-point took out from PAC3D of software ISFEL3D. Results obtained in the two methods made an agreement. It is found that larger gap impedance can be obtained by employing calculated cavity configuration.
