Abstract
Front cover image: The rapid growth of wireless digital communication has heightened electromagnetic (EM) pollution risks. One-dimensional metals, with excellent conductivity and network formation, are ideal for EM energy attenuation. However, high conductivity causes impedance mismatch, limiting EM wave dissipation. This paper presents Sn whiskers synthesized from the decomposition of MAX phase and then transformed into Sn@C cables via dopamine polymerization and annealing. This structure enhances impedance matching and introduces heterojunctions, boosting the effective absorption band to 7.4 GHz and achieving a 27.85 dB m2 radar cross section reduction, indicating excellent stealth capability. This work provides insights into the broadbanding of low-dimensional absorbers. Article number: 10.1002/cey2.638
