1) Near-field method
近场方法
2) approximate field-theory analysis
近似的场论方法
1.
The dispersion equation of the structure was derived by means of an approximate field-theory analysis, in which the continuous profile of the groove was approximately replaced by a series of rectangular steps, and the field continuity at the interface of two neighboring steps and the matching conditions at the interface between the groove region and central region we.
采用近似的场论方法,用一系列相连的矩形阶梯来近似代替光栅上任意槽形的槽的连续轮廓,利用各阶梯面上导纳的匹配,以及槽与互作用区的连续和匹配条件,获得了任意形状槽圆柱光栅周期结构的色散方程,并讨论了系统结构参数变化对系统色散特性的影响。
