摘要
光栅中的电磁场是哈密尔顿系统，利用其中存在守衡量的特性可以得出色散与反射系数间的简单关系，进而分析出光栅所固有的一些谱特性。
The electronic and magnetic field in a grating is a Hamiltonian system. Its conserved quantities are used to get the relation between the dispersion and the reflective coefficient. This is helpful for the analysis of spectral characteristics of the gratings.
