摘　　要：电磁超材料是由亚波长微结构周期排列而成的人工复合材料,对电磁波有很强的传导调控作用或吸收作用,在航空武器装备隐身设计领域被广泛研究。本文首先介绍了电磁超材料的概念,综述了电磁调控型超材料、电磁吸收型超材料、主动可调型超材料和智能超材料的最新研究进展;然后介绍了航空电磁偏折超材料、电磁吸收超材料和频率选择超材料的隐身机理及应用研究现状,分析认为隐身机理丰富和可设计性强是电磁超材料有别于传统吸波材料的主要优势。从拓展吸波频谱、增强吸波性能、吸波智能可调三方面对电磁超材料提出发展建议,包括吸波频谱进一步向红外、激光、紫外波段拓展,宽频吸波性能进一步提升,吸波频带智能可调。Electromagnetic metamaterial is an artificial composite composed of periodic subwavelength microstructure,which has a strong conduction regulation or absorption effect on electromagnetic wave,and it has been widely studied in the field of stealth design of aviation weapons and equipment.In this paper,the concept of electromagnetic metamaterial is introduced firstly,and the latest research progresses of electromagnetic control metamaterial,electromagnetic absorbing metamaterial,active tunable metamaterial and intelligent metamaterial are reviewed.Then,the stealth mechanism and the application research status of electromagnetic deflection metamaterial,electromagnetic absorbing metamaterial and frequency selective metamaterial are introduced.It is analyzed that the rich stealth mechanism and the strong designability are the main advantages of electromagnetic metamaterials as distinct from the traditional absorbing materials.For the development of electromagnetic metamaterial,this paper puts forward three suggestions from expanding the absorbing spectrum,enhancing the absorbing performance,and smart tunable of absorbing ability,specifically including the expansion of absorbing spectrum to infrared,laser and ultraviolet band,further improving the broadband absorbing ability,and intelligent adjusting the absorbing frequency band.
