Propagation and tunneling of polarized light through gradient nanophotonic barriers, formed by continuous distributions of dielectric susceptibility ε(z) across the films, fabricated from dielectrics without free carriers, are considered. The decisive influence of giant artificial heterogeneity - induced non -local dispersion, both normal and abnormal, stipulated by the gradient and curvature of distribution ε(z), is shown to provide the polarization - dependent tunneling of radiation in any spectral range in need. New trends in technology of sputtering of gradient silicon films of controlled distribution of ε(z) on the substrate are developed, and the parameters of films, fabricated by means of these technologies, are measured. Special methods for polarimetric testing of gradient dielectric nanofilms, based on new exact analytical solutions of Maxwell equations for inclined incidence of polarized waves, are presented. New types of dispersive elements for photonic crystals, based on polarization effects in gradient dielectric nanofilms, including, e.g., mode selectors, miniaturized phase shifters and large angle polarizers, are discussed.
