    Abstract

    Metamaterials, due to their incomparable capabilities in manipulating effective material parameters, have been attracting worldwide attention in the past two decades. In previous works, most metamaterials and metasurfaces focused on the material parameter steering in a continuous scale, which is regarded as “analog metamaterials/metasurfaces.” Since Cui et al. proposed the concept of digital coding and programmable metamaterials/metasurfaces in 2014[1], a new perspective to design metasurfaces has been opened up, bridging between electromagnetic physics and digital information for the first time. Coding metamaterials/metasurfaces have presented diverse physical principles and applications in electromagnetic field manipulations, further deriving many sub-directions. In the process of exploration and enrichment in recent years, the coding metasurface has continuously demonstrated its powerful ability in information regulation and combination. Using this as a strong connection, the field has gradually grown into a new system called information metamaterials/metasurfaces[2,3].
