title: Analytical model of the optical response of periodically structured metallic films: Comment.
abstract: A comparison is made between rigorous numerical results and a recently proposed analytical method for modeling light diffraction by lamellar diffraction gratings. The conclusion is that the analytical model is quite restrained in its applicability and can be misleading in determining the behavior of the grating efficiencies.
