Abstract

Abstract : A novel optical encryption scheme based on single‐sized nanostructures storing multiple meta‐images into different encryption levels is originally proposed and realized by Juan Deng, Bo Yan, and co‐workers, as shown in article number 2200949 . By introducing a camouflage strategy into Malus metasurfaces, this research ensures that even if the camouflage information is decrypted, the real information is still safe. The simple structure, high security, and scalability endow the metasurface with great potential in encryption applications and provide new insights for other related fields.
