摘要
本文设计了一种可用于航空器电磁防护和智能隐身的光学透明的宽带超材料柔性吸波器。该吸波器采用三明治结构,使用透明导电材料氧化铟锡(ITO)代替金属作为顶层表面谐振结构和底层铺地所用材料,透明柔性材料聚对苯二甲酸乙二醇酯(PET)作为介质层,可以在2.0～5.2GHz内达到85%以上的吸收率。试验测试吸收谱结果与仿真结果相符合。同时,HFSS软件仿真结果显示该吸波器对极化角度不敏感,且入射角度低于30°时,吸收率变化很小,在实际应用中有很好的灵活性。该透明柔性宽带微波吸波器精确覆盖了常用的WiFi频段,可有效减小移动电子设备等常见干扰源对飞机造成的电磁干扰。
An optical-transparent broadband metamaterial flexible absorber that can be used for aircraft electromagnetic protection and intelligent stealth is designed in this paper. The absorber used the typical sandwich structure, and the transparent and conductive material Indium Tin Oxide(ITO) was used as the surface resonance structure and the ground, and the transparent material Polyethylene terephthalate(PET) was used as the dielectric layer. After structure optimization, the transparent broadband absorber showed high absorption(>0.8) from 2.0 GHz to 5.2 GHz. The experiment data showed good agreement with the simulation results. At the same time, the HFSS software simulation results showed that the absorber was not sensitive to the polarization angle, and the absorption changed little when the incident angle was lower than 30°, thus can satisfy versatile application requirements in practice. The transparent flexible broadband microwave absorber accurately covers the commonly used WiFi frequency band, and can effectively reduce the electromagnetic interference caused by common interference sources such as mobile electronic devices to the aircraft.
