从耦合模式模型(COM)方程出发,得到周期短路栅格与开路栅格中场分布的解析表达式,利用给出COM参量,研究了场分布的特征,通过对解析表达式和典型频率的场分布图形的研究,找到与场分布有关的一些特征量,并将这些特征量与COM参量通过一定的解析关系联系起来。在用其他方法得到了周期栅格中的场分布时,可拟合场分布包含的这些特征量从而得出对应的COM参量。该文给出了一种从场分布提取随频率变化的COM参量的方法。
Starting from the coupled mode model (COM) equation, the analytical expressions of the field distribution of periodic short-circuit grids and open grids are obtained. By giving the COM parameters, the field distribution characteristics are studied. By analyzing the expressions and typical frequency fields Distribution of graphics to find some of the characteristics associated with the field distribution of the amount of these characteristics and COM parameters through a certain analytical relationship. When the field distribution in a periodic grid is obtained by other methods, the corresponding distributions of these characteristics can be fitted to obtain the corresponding COM parameters. This paper presents a method of extracting the COM parameters from the field distribution as a function of frequency.
