All‐in‐One Multispectral Stealth Device for X‐Band Radar, Visible, and Near‐Infrared Spectra

open access: yesNanophotonics, Volume 15, Issue 8, 24 April 2026.
This study demonstrates an all‐in‐one multispectral stealth platform seamlessly combining an electrochromic device with a patterned ITO metasurface. The device achieves reversible, voltage‐driven visible‐to‐near‐infrared modulation through redox reactions, simultaneously maintaining X‐band radar absorption. The performance of this all‐in‐one device was
