Multidimensional Information‐Encoding Metasurface for Key‐Concealed Physical‐Layer Secure Communications

ABSTRACT Metasurface‐based secure communication has been extensively investigated, offering a new avenue for direct wireless physical‐layer encryption. However, most existing schemes are still restricted to single‐dimensional electromagnetic encryption and rely on key pre‐distrib...

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...
