Rigorous coupled-wave analysis (RCWA) is a semi-analytical method in computational electromagnetics that is most typically applied to solve scattering from periodic dielectric structures. It is a Fourier-space method so devices and fields are represented as a sum of spatial harmonics. WebHere, I typically use nG=11..15, but check convergence for tests cases up to nG=23. This was done, e.g. for holey metal films: Article Spatial dispersion in two-dimensional …
