白金ナノコイル網のテラヘルツ電磁波吸収特性

抄録

With the development of advanced information society, electromagnetic waves used in various electronic devices have spread to high-frequency band, and new electromagnetic wave absorbers are required. Recently, the authors developed a method for fabricating transparent metallic nanocoil web. The transparent metallic nanocoil web is expected to be applied as a transparent electromagnetic wave absorber. In this study, the transmittance and the reflectance of Pt nanocoil web in the terahertz region were measured using a Fourier transform infrared spectrophotometer, and the absorption was calculated. The absorption was found to increase with the increasing density of Pt nanocoil web. Furthermore, it was found that it has superior electromagnetic wave absorption characteristics and high transparency as compared with Pt nanofiber web and Pt film.
