摘要
慢波结构是微波管重要的部件,它是电子注与高频场相互作用进行能量交换以实现微波振荡或放大的场所。随着对微波管性能越来越高的要求,微波管慢波结构的效率和性能要求也随之提高。文中首先分析了如何求解微波管慢波结构的高频特性,并在此基础上使用了HFSS以及CST MWS等软件对两种新型微波管慢波结构(环杆慢波结构、折叠波导慢波结构)的高频特性(色散特性、耦合阻抗)进行了初步的仿真研究,并通过对结果的分析比较了两个结构的特性。
The high-frequency circuit (HFC) is one of the most important parts in the microwave tubes, where the electron beam and the electromagnetic wave interacts each other. As the requirement of the performance of the microwave tubes improves, the efficiency and performance of the HFC are also required to be improved. In this paper, we simulate and study the high-frequency characteristic (i.e. dispersion, coupling impedance etc.) of two high-frequency circuits of microwave tubes (ring bar slow-wave structure, folded waveguide slow-wave structure) with HFSS and CST MWS software. At last we also compared the results of two different structures.
