Fully Polarimetric Radar Cross‐Section and High‐Resolution Range Profile Co‐Modulation via Diversely Time‐Modulated Metasurface

Nanophotonics, Volume 15, Issue 14, 27 July 2026.
A diversely time‐modulated metasurface enables broadband co‐modulation of fully polarimetric radar cross section and high‐resolution range profiles. By integrating anti‐parallel PIN diodes and programmable temporal coding, the platform dynamically redistributes scattering among HH/VV and HV/VH channels, generating tunable target weakening, false ...

Suppressing Stitching Errors in Full‐Sensor‐Plane Color Routers via Optical Structural Similarity

Nanophotonics, Volume 15, Issue 14, 27 July 2026.
Angle‐specific nanophotonic color routers are assembled from a library of inverse‐designed unit cells matched to local incidence angles. Optical structural similarity (OSS) constrains neighboring permittivity profiles during optimization, suppressing inter‐cell stitching errors without additional full‐wave simulations and enabling oblique‐incidence ...
