Metasurface Doppler Cloak for Broadband Radar Stealth

Advanced Physics Research, Volume 4, Issue 10, October 2025.
Suppressing the motion‐induced Doppler shift passes the target as part of the static clutter which is ignored by radars. Using a simple time‐modulation, frequency conversion is obtained from a metasurface‐based solution over a wide range. Referred to as a Doppler cloak, this work expands and validates such a varactor‐loaded prototype for broadband ...
