摘要: We present a novel antireflection approach utilizing planar metamaterials on dielectric surfaces. It consists of split-ring resonator array and metal mesh separated by thin spacer. The coating dramatically reduces the reflectance greatly enhances transmittance over wide range incidence angles narrow bandwidth. Antireflection is achieved tailoring magnitude phase shifts waves reflected transmitted at metamaterial boundaries, resulting in destructive interference reflection constructive transmission. can be very there no requirement for spacer constant.
