Laser-induced graphene (LIG) has become a promising stealth material due to its excellent electromagnetic loss characteristics in the terahertz and microwave bands (2-18 Ghz) and the advantages of low-cost large-scale manufacturing. With the rapid advancement of electromagnetic detection technologies toward multispectral and high-dynamic-range capabilities, there is an increasing demand for LIG-based stealth materials with superior absorption performance. The synergistic design of functional material doping and structural configurations has been identified as a critical approach to achieve high electromagnetic shielding performance in LIG-based composites. This article briefly reviews the developmental progress of LIG-based electromagnetic stealth materials, with a particular emphasis on doping technologies and shielding mechanisms tailored for stealth applications. Furthermore, we propose potential future development pathways for LIG-based stealth materials to facilitate their transition toward broader practical applications.
激光诱导石墨烯（LIG）因其在太赫兹和微波频段（2-18吉赫兹）具有优异的电磁损耗特性以及低成本大规模制造的优势，已成为一种有前景的隐身材料。随着电磁探测技术向多光谱和高动态范围能力的快速发展，对具有卓越吸收性能的基于LIG的隐身材料的需求日益增加。功能材料掺杂和结构构型的协同设计已被视为在基于LIG的复合材料中实现高电磁屏蔽性能的关键方法。本文简要回顾了基于LIG的电磁隐身材料的发展进展，特别强调了针对隐身应用定制的掺杂技术和屏蔽机制。此外，我们提出了基于LIG的隐身材料未来潜在的发展途径，以促进其向更广泛实际应用的转变。
