摘要: 从麦克斯韦方程组出发,运用电磁场的匹配条件,导出了双间隙谐振腔等效周期结构横磁模的色散关系及场分布表达式。然后通过数值计算,求出了双间隙谐振腔的谐振频率和场分布,并分析了谐振腔的结构尺寸对频率的影响,为C波段双间隙输出腔的设计提供了理论依据。Abstract: Starting from Maxwell’s equations for the fields, and using the matching conditions of electromagnetic fields, a cold dispersion equation and field solutions of an equivalent periodic structure pertaining to the double-gap resonator are derived. The dispersion equation and field solutions are employed to numerically calculate frequencies and field distributions, the effect of the resonant cavity size on frequency is discussed , and the theoretical basis for design of C-band double-gap output cavity is provided.
