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.
给出了无限长沟槽波纹表面任意入射角平面波散射的完整解。将电磁波分解为快模和慢模表示，并通过模式匹配法求解。我们求解了任意入射角下各偏振分量的零阶衍射效率和相位。我们的结果验证了其他人之前发表的特殊情况，并说明了与衍射过程相关的偏振之间的相位偏移作为入射角的函数。
