摘要: 利用等效电路法和高频分析软件（HFSS）对A6相对论磁控管谐振系统进行了理论计算与模拟分析，着重考虑了相对论磁控管端帽的引入对谐振频率的影响。模拟和冷测均表明：相对论磁控管端帽的引入将对谐振频率造成一定影响，在端帽的某些尺寸下，同一模式将会分裂出两个谐振频率。这将加剧磁控管内部的模式竞争而不利于磁控管的工作。Abstract: A6 relativistic magnetron`s resonated system is calculated and simulated by equivalent circuit and high frequency structure simulator (HFSS of Agilent), and the effect of end cap to resonated frequency is especially paid attention to in this paper. Results of simulation and cold test show that the end cap will cause resonated frequency to change and in some case, the end cap will result in that two different resonated frequencies satisfy the same resonated mode. It will make mode compete more acute and disadvantage to work of relativistic magnetron.
