Grid adaptation for modeling trapezoidal difractors by using pseudo-spectral methods for solving Maxwell equations
We propose a series of successive one-dimensional coordinate transformations to construct an adaptive two-dimensional grid for the problem of diffraction on a grating with a trapezoidal tooth. Special attention is paid to the smoothness of the grid and grid refinement in domains of large solution gradients.
