摘　　要：基于透明导电材料氧化铟锡(ITO)、高透光的聚对苯二甲酸乙二醇酯(PET),设计并实现了光学透明超宽带雷达与红外兼容隐身的复合超表面。该结构由两个专门设计的光学透明超表面组成,由内到外依次为雷达吸波层、红外低发射层。通过调节谐振器尺寸和ITO的方阻实现了微波段8.0~32.0 GHz频带内吸收率高于90%的宽带吸波。利用高ITO占空比的容性频率选择表面,实现了微波段高透过率与红外波段低发射率,并进一步研究了其红外辐射特性。该结构具备较好的超宽频雷达吸波性能、低红外发射率与光学透明特性。Based on the transparent conductive material Indium Tin Oxide(ITO)and highly transparent Polyethylene Terephthalate(PET),optically transparent ultra-wideband radar and infrared compatible stealth hybrid metasurfaces were achieved.Two specically designed optically transparent metasurfaces were combined to realize radar and IR bi-stealth.One was designed to control the microwave absorption though properly modifying the impedance and resonance peaks of the meta-atom.The other was empolyed to control the IR radiation.The absorptivity in the microwave band 8.0~32.0 GHz band is greater than90%,and its infrared stealth performance and heat radiation characteristics are further studied.
