Design of multilayer coatings containing metal island films

Thin metal island films exhibit unique optical properties and possess a high potential in design and fabrication of multilayer coatings with sophisticated spectral performances over wide wavelength and angular ranges. Optical properties of these films are dependent on film thickness. In the present study we consider and solve a problem of designing multilayers which reflect different colors from their front and back sides and have specified average transmittance values. Additionally, in many cases the reflected colors are stable to variations of the incidence angle. In the design process we use optical constants of Ag metal island films, that were carefully determined based on recently proposed characterization approach.
