本文通过求解缓变截止波导结构的相对场分布计算其输入反射系数,结合网络理论,提出一种对周期性慢波结构周期单元和缓变截面波导开放腔进行数值分析的新方法。方法简便通用,结果与实验甚为一致。
In this paper, the input reflection coefficient is calculated by solving the relative field distribution of slow-moving cutoff waveguide. A new method for numerical analysis of periodic cavity with slow-wave structure and open cavity with slowly-varying-section waveguide is proposed based on network theory. The method is simple and universal, the result is very consistent with the experiment.
