光栅的矢量模态理论及其应用研究课题系国家自然科学基金项目。主要开展对光栅衍射问题的研究,推导出理想状态下光栅的衍射效率与偏振态,从而与实际光栅衍射效率相对照,暴露二者之间的差异,有助于光栅工艺技术的提高。
Grating vector mode theory and its application research project of the National Natural Science Foundation of China project. The main work is to study the grating diffraction problem and derive the diffraction efficiency and polarization state of the grating in the ideal state. Compared with the actual grating diffraction efficiency, the difference between the two is exposed, which contributes to the improvement of grating technology.
