WebScattering from metallic and dielectric rough surfaces is discussed by Saillard and Maystre [11], using the integral theory of metallic and dielectric gratings. Wolff [12] has reported diffuse-reflectance model for smooth dielectric surfaces. Light reflectance from randomly oriented convex particles with rough surfaces has been WebWith all-dielectric reflectors, the energy that is not reflected is instead transmit ted, since there is no absorption. Figure 1 shows the computed reflectances for Quarter-Wave (QW) designs based on two different high-index materials, tantala and titania, and used at zero incidence angle. Reflectance >99.8% is theoretically possible.
