Abstract Multiplexing and dynamic reconfigurable metasurfaces have been extensively studied to enhance optical system capacity in response the challenges posed by exponential growth of information. Among them, mechanically strategy offers a cost-effective low-complexity approach for enhancement. However, channel numbers achieved current studies are insufficient practical applications because inadequate mechanical transformations suboptimal optimization methods. In this article, diffractive magic cube network (DMCN) is proposed advance multiplexing metasurfaces. We utilized deep neural (D2NN) model jointly optimize subset channels generated combination three operations, permutation, translation, rotation. The 144-channel holograms, 108-channel single-focus/multi-focus, 60-channel orbital angular momentum (OAM) beam/comb generation were numerically experimentally validated using spatial light modulator (SLM) reflective mirror. Our not only provides novel paradigm improve metasurface super-high level with low crosstalk, but also paves way new advancements storage, computing, communication, photolithography.

Abstract Pursuing higher data rate with limited spectral resources is a longstanding topic that has triggered the fast growth of modern wireless communication techniques. However, massive deployment active nodes to compensate for propagation loss necessitates high hardware expenditure, energy consumption, and maintenance cost, as well complicated network interference issues. Intelligent metasurfaces, composed number subwavelength passive or meta-atoms, have recently found be new paradigm actively reshape environment in green way, distinct from conventional works passively adapt surrounding. In this review, we offer unified perspective on how intelligent metasurfaces can facilitate three manners: signal relay, transmitter, processor. We start by basic modeling channel evolution passive, metasurfaces. Integrated various deep learning algorithms, cater ever-changing environments without human intervention. Then, overview specific experimental advancements using conclude identifying key issues practical implementations surveying directions, such gain knowledge migration.
