Abstract

In this article, we propose a novel transparent tunable water-based metamaterial (TTWM) to realize multispectral camouflage of visible light, infrared and microwave. By modulating the injection and discharge of pure water, the broadband switching function between the microwave absorbing state (6.0–34.9 GHz for transverse electrical (TE) mode and transverse magnetic (TM) mode) and the reflecting state (10.7–28.2 GHz) is realized. In combination with the inherent characteristics of the material, the TTWM achieves low emissivity (~0.25) in the infrared band (3–

$14~\mu $

m) and an average optical transparency of 62%. Furthermore, it possesses wide-angle stability, polarization insensitivity, and excellent thermal stability. The unique attributes of this structure are substantiated through numerical simulations and experimental validation, indicating that our designed model holds significant promise for applications in multispectral camouflage field.

用于微波红外伪装的透明可调水基超材料

本文提出了一种新型透明可调谐水基超材料（TTWM），可实现可见光、红外和微波的多光谱伪装。通过调制纯水的注入和排放，实现了微波吸收态（横向电（TE）模式和横向磁（TM）模式的6.0 ~ 34.9 GHz）和反射态（10.7 ~ 28.2 GHz）之间的宽带切换功能。结合材料的固有特性，TTWM在红外波段（3 - $14~\mu $ m）实现了低发射率（~0.25），平均光学透明度为62%。此外，它还具有广角稳定性、偏振不敏感性和优良的热稳定性。通过数值模拟和实验验证证实了该结构的独特属性，表明该模型在多光谱伪装领域具有重要的应用前景。

期刊介绍： The IEEE Transactions on Microwave Theory and Techniques focuses on that part of engineering and theory associated with microwave/millimeter-wave components, devices, circuits, and systems involving the generation, modulation, demodulation, control, transmission, and detection of microwave signals. This includes scientific, technical, and industrial, activities. Microwave theory and techniques relates to electromagnetic waves usually in the frequency region between a few MHz and a THz; other spectral regions and wave types are included within the scope of the Society whenever basic microwave theory and techniques can yield useful results. Generally, this occurs in the theory of wave propagation in structures with dimensions comparable to a wavelength, and in the related techniques for analysis and design.
