Superelastic Magnetic Aerogel Valve Modulates Infrared‐Radar Stealth

ABSTRACT The transparency of modern battlefields, dominated by multispectral surveillance, demands adaptive camouflage that can dynamically evade both infrared and radar detection. However, the fundamental conflict between the high electromagnetic loss required for radar stealth and the low emissivity essential for infrared stealth has long impeded progress toward such intelligent and compatible systems. Herein, we break this limitation through superelastic magnetic nanofiber aerogels (MNFAs) fe
