This greatly enlarges the domain of applicability of two-dimensional Fourier-methods in light scattering applications since the generalized source method has much less numerical complexity than widely used Fourier modal method. It is also demonstrated on numerical examples that for pure dielectric structures the use of lossy perfectly matching layers is not necessary for removing the effects of periodicity and taking of a large grating period is sufficient.
