Abstract

This work proposed a fast inverse design method for microwave and infrared (IR) bi-stealth metamaterials based on the equivalent circuit model (ECM). Using this method, we designed a microwave and IR bi-stealth metamaterial by deploying a multilayered structure of the indium tin oxide (ITO) film based metasurface. First, the IR emissivity of the ITO film was calculated in the framework of the ECM. Then, an ITO metasurface was proposed to implement low IR emission and high microwave transmission simultaneously. Based on the ECM of the square patch, the ECM of the whole metamaterial was established at the microwave band. An inverse design program was built by incorporating the ECM with genetic algorithm (GA). Structure parameters of the metamaterial were optimized by GA to achieve the broadest microwave stealth bandwidth for the given thickness. Finally, the sample of the optimized bi-stealth metamaterial was prepared and tested. The calculated, simulated, and measured results are in good agreement, showing that such a metamaterial has an IR emissivity of 0.18 in the band from 3 to 14 μm and an efficient microwave stealth band from 4.8 to 17 GHz with a thickness of 4.9 mm. The proposed method will benefit the design and application of microwave and IR bi-stealth metamaterials.
基于等效电路模型的微波和红外双隐形超材料快速逆向设计
这项研究提出了一种基于等效电路模型(ECM)的微波和红外(IR)双隐形超材料快速逆向设计方法。利用这种方法,我们设计了一种基于氧化铟锡(ITO)薄膜超表面的多层结构的微波和红外双隐形超材料。首先,在 ECM 框架内计算了 ITO 薄膜的红外发射率。然后,提出了一种同时实现低红外发射和高微波传输的 ITO 元表面。在方形贴片 ECM 的基础上,建立了整个超材料在微波频段的 ECM。通过将 ECM 与遗传算法(GA)相结合,建立了反向设计程序。通过遗传算法优化超材料的结构参数,以在给定厚度下获得最宽的微波隐形带宽。最后,制备并测试了优化后的双隐形超材料样品。计算、模拟和测量结果都非常吻合,表明这种超材料在 3 至 14 μm 波段的红外发射率为 0.18,在 4.8 至 17 GHz 的有效微波隐身频段内厚度为 4.9 毫米。所提出的方法将有利于微波和红外双隐形超材料的设计和应用。
