This paper describes in a very easy and intelligible way, how the diffraction efficiencies of binary dielectric transmission gratings depend on the geometrical groove parameters and how a high efficiency can be obtained. The phenomenological explanation is based on the modal method. The mechanism of excitation of modes by the incident wave, their propagation constants and how they couple into the diffraction orders helps to understand the diffraction process of such gratings and enables a grating design without complicated numerical calculations.
本文以一种非常简单易懂的方式描述了二元介质透射光栅的衍射效率如何取决于几何槽参数，以及如何获得高效率。现象学解释基于模态方法。入射波激发模式的机制、它们的传播常数以及它们如何耦合到衍射级次，有助于理解此类光栅的衍射过程，并能够在不进行复杂数值计算的情况下进行光栅设计。
