摘要: 该文提出了一种用于回旋管的多波导输出结构。利用 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。Abstract: 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 TE01○ mode to the TE10□ mode can be reached with the bandwidth of about 3% at VSWR of less than1.5 for the TE01○ mode input.
