Calculation and simulation analysis of A6 relativistic magnetron`s resonated system

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.
