摘要

本文介绍了斜壁周期性结构分析的傅里叶模态方法的扩展，利用三维法向量场对不连续函数的乘积进行正确的傅里叶级数分解。数值试验表明，与传统的二维分解规则相比，改进后的方法收敛速度更快。

Fourier modal method for efficient modeling of periodically structured metasurfaces with unit cells of arbitrary shape

We introduce an expansion of the Fourier modal method for the analysis of periodic structures with oblique walls by using a three-dimensional normal vector field for the correct Fourier series factorization of products of discontinuous functions. Our numerical tests show that the improved method leads to faster convergence as compared to conventional two-dimensional decomposition rules.
