An optically transparent broadband metamaterial absorber (MA) containing an air layer and a water layer is proposed, which can absorb broad-band microwave and reduce infrared radiation at the same time. As a proof, a structure consisting of indium tin oxide (ITO) frequency selective surface (FSS), air layer, water substrate and ITO backplane was firstly designed. The simulation reveal that the structure can absorb wideband microwave with an efficiency of over 90% in the 14.4 GHz to 39.4 GHz frequency band, and it is optically transparent. This is consistent with the experimental results. In addition, the use of the water circulation system can significantly reduce the infrared radiation, thereby achieving infrared stealth. Due to its versatility and excellent performance, the proposed design is expected to find extensive applications in multi-spectrum stealth, such as glass windows for stealth devices, camouflage, etc.

一种用于雷达红外双隐身的光学透明宽带超材料吸收器

提出了一种包含空气层和水层的光学透明宽带超材料吸收器(MA),其可以吸收宽带微波并同时减少红外辐射。为了证明这一点,首先设计了一种结构,该结构由氧化铟锡(ITO)频率选择表面(FSS),空气层,水衬底和ITO背板组成。仿真表明,该结构在14.4 GHz至39.4 GHz频带内可以吸收宽带微波,效率超过90%,并且是光学透明的。这与实验结果一致。另外,使用水循环系统可以大大减少红外辐射,从而实现红外隐身。由于其多功能性和出色的性能,
