摘要 该文提出了一种用于回旋管的多波导输出结构。利用AnsoftHFSS高频计算软件,对这种结构进行了数值模拟,通过对各相关尺寸进行合理选择以及模式转换过程的优化,不仅有效实现了工作模式之间的输出转换,同时在一定程度上降低了竞争模式对工作模式的影响。在Ka波段,获得了对驻波比小于1.5情况下,从TE01到TE10模输出能量转换效率大于95.9%和带宽接近3%的结果。 In this paper, a multi-waveguide output structure for gyrotron applications is proposed. Numerical simulations are performed for this structure by using High Frequency Structure Simulator ( Ansoft HFSS ). The results show that the energy conversion efficiency of more than 95.9% from the TE°01 mode to the TE10 mode can be reached with the bandwidth of about 3% at VSWR of less than 1.5 for the TE01, mode input.
