Abstract
Domed Ag nano-hole/disk array films exhibit a reflectivity of less than 0.7 % over a wide spectral range (400-1000 nm) and even lower values down to 0.05 % with an oblique incidence angle; this unique optical response is attributed to three key factors: diffractive scattering loss on nanostructures, localized plasmonic absorption and curved surface (domed units).
