摘要
封面图片：无线数字通信的快速发展加剧了电磁污染的风险。一维金属具有优异的导电性和网状结构，是电磁能量衰减的理想材料。然而，高导电性导致阻抗失配，限制了电磁波的耗散。本文介绍了由MAX相分解合成Sn晶须，经多巴胺聚合和退火加工成Sn@C电缆。该结构增强了阻抗匹配并引入异质结，将有效吸收带提高到7.4 GHz，实现了27.85 dB m2的雷达横截面减小，表明了出色的隐身能力。这项工作为低维吸收器的宽带化提供了见解。物品编号：10.1002/cey2.638
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.
