WebThis article possibly contains original research. (October 2024) 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. WebIn order to obtain the reciprocal lattice vectors, one has to define the incident wavelength and real space unit cell size and scale the grid by these. This RCWA implementation works for arbitrary plane wave incidence conditions. However, $\theta$ should not be set to zero in order to avoid numerical singularities.
