中文摘要:
      提出一种液控可调透明吸波结构。该结构由双方环频率选择表面结构、透明介质层和导电底板构成。介质层包括上下两层液体介质填充层,通过注入不同电参数的液体介质,实现吸波结构吸收率的调控;通过注入不同颜色的液体介质,实现结构表面颜色的变化;采用液体介质循环注入方式和流速控制,可调控结构表面温度。提出的结构有望应用于光学、红外和雷达多波段融合伪装装备,同时为背景自适应伪装奠定基础。本文主要研究注入液体介质对吸波性能的影响规律。仿真结果表明:改变液体介质注入模式和介质种类可以在4~18 GHz 频带内实现10 dB 以上反射率大幅动态调控,并且该吸波结构具有同时对光学和红外特性进行调控的潜力。
英文摘要:
      A tunable transparent liquid-controlled absorbing structure is proposed. This structure consists of double square ring frequency selective surface(FSS) structure, transparent dielectric layer and conductive plate. There are two liquid medium filling layers(an upper and a lower) in this structure. Regulation of microwave absorptivity can be controlled by injecting liquid medium with different electromagnetic parameters; the surface color of the structure can be changed with the injecting liquid medium of different colors; the surface temperature of the structure can be controlled by circulating injection mode and flow rate control of the liquid medium. The proposed structure is expected to be applied to multiband camouflage technology, and it may be the foundation of the adaptive camouflage. This paper mainly studies the law of the influence of different liquid medium injection on the microwave absorption performance. The simulation results show that changing the injection mode and type of the liquid medium can achieve a large reflectivity adjustment of more than 10 dB in the 4-18 GHz frequency band, and the absorption structure has the potential to adjust the optical and infrared characteristics at the same time.
