| Research Abstract |
A periodic microstructure is built on a ultra violet curable resin by the UV nanoimprint method. A gold film is sputtered on the periodic microstructure. Assuming Kirchhoff's law, the maximum normal emissivity of the periodic microstructure is 0.6 near 10gm in the case of the gold film 200 nm thick the surface facing a sputter source. The periodic microstructure with the gold film contributes to the prevention of global warming.
