(a) Reflectance spectra at normal incidence of unpolarized light for PhC structures comprising of 2, 3, 5 and 7 layers of alternating Nb2O5 and MEL zeolite films deposited on glass substrate. In all samples the film close to the substrate is Nb2O5; (b) measured and calculated values of maximum reflectance as a function of number of the layers in the stack; and (c) dispersion curves of refractive index for Nb2O5 and MEL zeolite films.
