Abstract
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.
