A study of coupling between finite number of general-shaped grooves in electromagnetic plane-wave scattering problem is presented. The formulation for a single groove [1] is extended to two grooves. The importance of inclusion of coupling interaction between two grooves in scattering analysis is presented and its dependence on the grooves separation distance and the angle of incident of the electromagnetic field is demonstrated quantitatively. For larger angle of incident and smaller separation distance between grooves indicate larger discrepancy between between simulation results with and without inclusion of the coupling effects. Although the results presented here considers two grooves, the formulation can be extended to arbitrary number of grooves.
本文提出了一种关于电磁平面波散射问题中有限数量的一般形状凹槽之间耦合的研究。单个凹槽的公式[1]被扩展到两个凹槽。阐述了在散射分析中考虑两个凹槽之间耦合相互作用的重要性，并定量地证明了其对凹槽间距和电磁场入射角的依赖性。对于较大的入射角和较小的凹槽间距，包含和不包含耦合效应的模拟结果之间存在较大差异。尽管这里给出的结果考虑的是两个凹槽，但该公式可以扩展到任意数量的凹槽。
