Abstract:
We extend the Mayadas and Shatkes’s approach [Phys. Rev. B 1, 1382 (1970)] to study the optical properties
of polycrystalline metal thick films in the visible and far infrared range of the spectrum. We show that in this
range grain boundary scattering can account for the experimentally observed lowering of the film reflectivity as
the mean size of its constituent grains decreases.
