摘要
隐身复合吸波材料在军事、民用领域应用广泛,不仅可以为武器装备的隐身提供关键材料,而且可以用来避免电磁辐射污染.理想的吸波材料的要求是涂层薄、重量轻、吸波频带宽、吸波性能强.本文针对隐身复合吸波材料的应用进行了综述,首先简单介绍雷达吸波材料及其吸波方式,其次较详细地介绍了铁氧体、磁性金属、碳系材料、导电聚合物、超材料等隐身复合吸波材料的结构性质、电磁性能和每种材料在隐身复合吸波材料领域中的应用.相较单一材料,复合材料引入多种损耗机制,具有更好的磁损耗和介电损耗,兼顾良好的吸波性能和拓宽的应用范围.最后指出了雷达隐身复合吸波材料的发展趋势.
Stealth composite absorbing materials are widely used in military and civil fields.They can not only provide key materials for stealth of weapons and equipment,but also can be used to avoid electromagnetic radiation pollution.The ideal absorbing materials require thin coating,light weight,wide absorbing band and strong absorbing performance.In this paper,the application of stealth composite absorbing material are summarized.Firstly,the radar absorting materials and their absorting modes are briefly introduced.Secondly,the structural characteristics and electrongnetic properties of stealth composite absorting materials such as ferrite,magnetic metal,carbon material,conductive polymer,and metaraterial are introduced in detail,as well as the application of each material in the field of stealth compasite absorting materials.Compared with single material,the composite material which introduces many kinds of loss mechanism,has better magnetic loss,dielectric loss,good absorbing performance and wider application range.Finally,the development trend of thunder stealth composite absorbing material is pointed out.
