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. WebMar 9, 2024 · From the RCWA solver object docs ( RCWA Solver - Simulation Object – Ansys Optics ): "The tangent vector field option should only be used with MESH REFINEMENT set to conformal variant 0, 1, or 2." It looks like you are using staircase mesh refinement, please try changing that to a conformal variant option.

WebMultivariate Normal Deﬁnition: A random vector X2Rd is multinormal if for each v2Rd the random variable hX;viis univariate normal. Note: A constant c2R is regarded as N(c;0) Fact: If X= (X 1;:::;X d)t is multinormal then components X 1;:::;X d are univariate normal. In particular, E(X) and Var(X) are well deﬁned. Note: Converse is not true. 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.
