36‐Channel Spin and Wavelength Co‐Multiplexed Metasurface Holography by Phase‐Gradient Inverse Design (Adv. Sci. 28/2025)

High-Capacity Single-Cell Metasurface Holography In article number 2504634, Junsuk Rho, Cherry Park, and Youngsun Jeon introduce a high-capacity single-cell metasurface hologram that multiplexes 36 spin- and wavelength-dependent holographic images across the visible spectrum. The cover image illustrates this metasurface, which is optimized by inverse design to achieve high fidelity, low crosstalk, and enhanced image quality through noise suppression during the optimization process.
