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.

Characterization of electromagnetic wave polarization states is critical in various applications materials, biomedical, and imaging. The emergence metasurfaces opens up the possibility implementing highly integrated full-Stokes imagers. Despite rapid development, prevailing schemes on metasurface-based imagers require interleaved or cascaded designs, inevitably resulting performance deterioration, bulky size, complicating imaging procedure due to misalignment. To overcome these challenges, a non-interleaved shared-aperture metalens enabled by prior-knowledge-driven inverse design methodology proposed. can be directly deployed into imagers, performing high-accuracy diffraction-limited without other ancillary components, breaking intrinsic constraints efficiency resolution design. demonstrate this, W-band passive system, as an alternative solution, perform polarimetric imaging, which reduces reliance high cost complexity ortho-mode transducer broadband correlator traditional radiometers. Furthermore, with assistance 3D reconstruction method, feasibility multi-polarization information for contactless surface slope measurements explored. This work may open new paradigms imager designing broaden metasurface
