(a) Binary Cr/Sc multilayer model with total period thickness D and the individual layer thicknesses dSc and dCr. (b) Model with explicit gradual interfaces following a sinusoidal profile. The ideal interface profile is approximated through discrete sublayers as indicated in red, forming the actual gradual interface profile entering the electric field calculations. The thickness of the interdiffusion zones can differ for the top and bottom interface in each period. Their total thicknesses are given by sSc and sCr. The effective index of refraction for each layer is given by [\tilde{n}_{{\rm Sc}}] and [\tilde{n}_{{\rm Cr}}], respectively.
