Frozen Differential Scattering in Reconfigurable Complex Media

open access: yesLaser &Photonics Reviews, Volume 20, Issue 11, 5 June 2026.
A localized perturbation universally results in a rank‐one update of the scattering matrix of any complex medium. The resulting differential output wavefront is “frozen”: its spatial pattern is fixed (agnostic to the input wavefront). Experiments with a programmable‐metasurface‐parametrized wireless link validate frozen differential scattering and ...

Dynamic Multifunctional Metasurfaces Based on Passive Cascade Structure

open access: yesElectron, Volume 4, Issue 2, May 2026.
A dynamic multifunctional metasurface is proposed in this paper. Unlike mainstream multifunctional metasurface based on programmable metasurfaces, it consists of two passive metasurfaces, presenting a significant cost advantage. By controlling the displacement, different functions such as beam steering, focusing, and OAM wave generation can be realized
