    "abstract": "We report on design and fabrication of nano-composite metal-dielectric thin\nfilm coatings with high reflectance asymmetries. Applying basic dispersion\nengineering principles to model a broadband and large reflectance asymmetry, we\nobtain a model dielectric function for the metamaterial film, closely\nresembling the effective permittivity of disordered metal-dielectric\nnano-composites. Coatings realized using disordered nanocrystalline silver\nfilms deposited on glass substrates confirm the theoretical predictions,\nexhibiting symmetric transmittance, large reflectance asymmetries and a unique\nflat reflectance asymmetry.",
