Advanced Metasurface Material Based Information Encryption

Information security is critical for anti-counterfeiting technology and information storage. Information encryption using advanced metasurface material is featured with high capacity, multiple channels, and secret transmission, which has emerged as a key application area of intelligent materials and advanced manufacturing. This project aims to develop a metal-dielectric hybrid metasurface, consisting of well-defined sub-wavelength pixels, to realize information encryption with new features, including the realization of encoding multiple information in a single metasurface chip, the information integration of both printing and holographic images, and secret transportation of multi-channel information.
