Mechanically reconfigurable metasurfaces enable high‐capacity optical storage and holography due to low cost/complexity. A differentiable inverse design framework maps meta‐atom geometries to multichannel optical responses via deep neural networks. Rotatable cascaded metasurfaces optimized through this pipeline achieve pixel‐level holography with 288 ...

Structured illuminations can unlock hidden quasi‐BIC modes in Fano‐resonant metasurfaces, enhancing the sensitivity to nanoscale perturbations. By analyzing the eigenmode spectrum of a dielectric metasurface and applying information theory, tailored wavefronts can be engineered that selectively excite otherwise inaccessible modes.

Terahertz Encryption With a Polarization‐Sensitive Metasurface
We propose a dual‐functional terahertz encryption metasurface that enables independent information retrieval in both the near field and the far field within a single device. In the near field, polarization‐selective amplitude modulation reveals textual patterns, whereas in the far field, phase engineering encodes multiple digital data in focal‐spot ...

Dispersion‐Engineered Broadband Transparent Meta‐Cloak
Achieving broadband performance remains a critical challenge in engineering physics. Here, theoretical derivation shows that the core phase compensation conditions for broadband transparent cloaking exhibit dispersive characteristics. A novel broadband transparent cloaking paradigm via dispersion engineering is proposed, and a meta‐cloak that realizes ...
