We extend the Mayadas and Shatkes’s approach @Phys. Rev. B 1, 1382 ~1970!# to study the optical propertiesof polycrystalline metal thick films in the visible and far infrared range of the spectrum. We show that in thisrange grain boundary scattering can account for the experimentally observed lowering of the film reflectivity asthe mean size of its constituent grains decreases
