Multi‐Channel Holography Enabled by Interlayer‐Correlated Liquid Crystal Elements for Nested Optical Encryption

ABSTRACT Liquid crystal (LC) planar devices have emerged as an attractive ultra‐thin platform for optical encryption. However, most existing LC‐based holographic encryption schemes rely on conventional multiplexing strategies with limited design freedom and weak interlayer collab...

Pixel‐Level Reconfigurable Pancharatnam–Berry Phase Induced by Inter‐Layer Coupling of Isotropic Metasurfaces

ABSTRACT The growing demand for dynamic electromagnetic wave control has accelerated the development of programmable metasurfaces. However, conventional approaches that rely on active components such as pin diodes, varactor diodes, and liquid crystals often suffer from limited mo...
