本文给出了任意入射情况下平面波在无限长槽纹表面上散射的完整解。将电磁波分解为快、慢两种模态，采用模态匹配法求解。我们解决了零级衍射效率和每个偏振分量的相位为任意入射角。我们的结果验证了特殊情况下，以前发表的其他人，并说明了与衍射过程中的入射角的函数的偏振之间的相移。
A complete solution of plane-wave scattering from a groove-corrugated surface of infinite extent for arbitrary incidence is presented. The electromagnetic wave is decomposed into fast and slow modal representation, and the solution is accomplished through the use of the mode-matching method. We solved for the zero-order diffraction efficiency and the phase of each polarization component for arbitrary incident angles. Our results have verified special cases previously published by others and have illustrated the phase shift between polarizations associated with the diffraction process as a function of the incident angles.
