【摘要】 设计并研制出一种基于超材料的宽带微波/红外兼容隐身结构器件，该结构包括基于氧化铟锡（ITO）薄膜制备出的红外隐身层、微波吸收层和微波反射层，红外隐身层由圆环镂空结构的频率选择表面组成，微波吸收层由周期和方阻均不同的方环结构组成，微波反射层由连续的导电薄膜组成。各层由厚度不同的聚甲基丙烯酰亚胺（PMI）隔开。结果表明此结构能够在2～18.6 GHz范围内实现90%以上的吸收，其红外发射率低于0.3。更多还原

【Abstract】 A radar/infrared compatible stealth structure based on metamaterial was successfully designed in this paper,and the structure consists of an infrared stealth layer(IRSL),two microwave absorption layers(MAL)and a microwave reflection layer(MRL)based on indium tin oxide(ITO)film. The IRSL is composed of frequency selective surface of ring hollow structure. The MALs are composed of square ring structures with different period and square resistance. The MRL is composed of continuous conductive film. Each layer is separated by a polymethacrylimide(PMI)materials with different thickness. Experimental results show that the structure can achieve more than 90% microwave absorption in the range of 2～18. 6 GHz,and its infrared emissivity is lower than 0. 3.更多还原
