Abstract

Abstract : Information Encryption In article number 2201468, Zhang‐Kai Zhou and co‐workers present the idea of fully utilizing all the degrees of freedom at the inter‐meta‐atom level for advanced metasurface design. With such idea, we not only greatly expand the image information storage capacity of metasurfaces, approaching the theoretical limit, but also enable a double‐key‐secured metasrface encryption technology with the advantages of high safety and large capacity for secret transportation.
