摘要
通过对光栅电磁理论发展历史的回顾,概述了一维衍射光栅电磁理论的发展历程与现状。通过一维光栅与双周期衍射光栅的结构参数的对比与实例的研究,指出双周期衍射光栅在应用上比一维衍射光栅有更加优越的性能;同时通过两种光栅编程仿真效果也表明:双周期衍射光栅理论的发展还不成熟,不能像一维光栅理论那样,作为研究光栅特性及器件设计的理想工具。最后基于对多种双周期光栅电磁理论的研究对比,总结了双周期光栅理论发展现状以及对以后的展望。
Through the review of the history of the grating electromagnetic theory,the development process and present situation of electromagnetic theory of one-dimensional diffraction grating development are introduced.Comparing the parameters between one-dimensional gratings and dual-period diffraction grating and researching on the several examples,figuring out that in contrast to one-dimensional diffraction grating,the dual-period diffraction gratings has more excellent performance in application;And watching results of simulating of two kinds of grating show that the theory of dual-period diffraction grating development is not mature enough,which is not as the theory of one-dimensional grating,to apply on research of characteristics and design of grating as a ideal tool.Finally based on the comparison in varieties of electromagnetic theory of dual-period grating,present situation and the prospect of the theory development of double periodic grating are presented.
