利用场匹配法得到了类磁控管结构的色散关系以及场函数表达式的同时, 利用高频电磁场分析软件验证了所得结果正确性, 并改变结构参数考察了截止频率的变化情况. 最终结果表明: 在保证其他参量不变的前提下,π模截止频率随外半径的减小, 内半径的增大或谐振腔数的增多而提高, 随谐振腔张角的增大而降低. 所得结果对于分析同轴辐射相对论磁控管的模式转换和传输特性奠定了基础.

Magnetronlike structure is a non-cathode magnetron waveguide structure. It is the basic configuration of relativistic magnetron with axial extraction (MDO). First, the dispersion relation and the field expression of the magnetronlike structure are obtained by the field matched method. Then, the results are proved by the high electromagnetic field analysis software, and the cutoff frequency is studied by changing the structure parameters. The final results show that with keeping the other parameters constant, the π mode cutoff frequency can be promoted by reducing the outer radius, enlarging the inner radius or increasing the number of the cavities. Enlarging the cavity angle will reduce the π mode cutoff frequency. The outcomes produced in this paper will play a fundamental role in the theoretical analysis on the mode conversion and transmission of the relativistic magnetron with axial extraction.-
