Frozen Differential Scattering in Reconfigurable Complex Media
Laser &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 ...
