Fourier modal method for relief gratings with oblique boundary conditions.
Oblique boundary conditions are introduced in the Fourier modal method at each slice of the staircase decomposition of an arbitrary profile of a dielectric corrugation grating. The precision and convergence improvement are demonstrated by comparison with reference methods.
