摘　　要：雷达吸波材料能够有效地抑制透射波和反射波,因而被广泛应用于隐身、电磁屏蔽和兼容以及无线通信等领域。受制于材料的电磁频散特性,传统吸波材料的宽带低频吸波性能难以进一步提高。近年来,随着超材料结构设计的不断发展,基于超材料构架设计实现的宽带电磁吸波,由于具有更加灵活的电磁调控能力,因而在其电磁性能提升方面具有更大拓展空间。围绕雷达吸波超材料的最新研究进展,结合电磁吸波超材料的发展背景、设计原理和性能表征方面的内容,着重介绍了基于多谐振叠加吸波结构、超材料与传统材料复合吸波结构、三维阵列吸波结构以及人工表面等离激元吸波结构设计的宽带雷达吸波超材料,并对于未来雷达吸波超材料的发展趋势做进一步展望。Radar absorbing materials(RAM)can effectively inhabit the transmitted waves and the reflected waves widely applied in the field of stealth technology,electromagnetic shielding and compatibility,as well as wireless communications.Suffering from frequency dispersion of electromagnetic parameters,the traditional EAMs still be up against a challenge in further improvement of broadband absorption in the low frequency.Recently,with the development of meta-material design,the achievement of broadband absorption based on meta-material configurations exhibits more performance improvement due to its flexible capability of electromagnetic manipulation.The paper centers on the research progresses in radar absorbing materials based on meta-material structure with the aid of development background,design principles and property characteristic.Specifically,the broadband radar absorbing meta-materials are in detail introduced based on the multi-resonance-integrated absorbing structure,meta-material absorbing structure combined with traditional material,three-dimensional array absorbing structure,as well as spoof surface plasmon polaritons absorbing structure.Furthermore,the paper looks forward to the future of the broadband radarabsorbing meta-material.
