Abstract：With the continuous enhancement of modern detection technologies,the joint detection tech-niques of visible light,infrared,and radar have been widely applied.How to achieve excellent stealth per-formance simultaneously in multiple frequency bands has become a key challenge.For the above-men-tioned reasons,this paper proposes and verifies a multifunctional flexible meta-surface in integrating spa-tially tunable infrared emissivity and radar cross-section(RCS)reduction.This meta-surface has both functions of infrared camouflage and radar stealth.Its sample structure is composed of aerogel felt/ITO/Air/PET/ITO from bottom to top successively.The functional layer is designed by etching ITO patch units on PET to form an encoded meta-surface.The surface achieves RCS reduction through microwave diffuse reflection and spatially tunable infrared emissivity by adjusting the ITO duty cycle.The simulation and experimental results show that the sample can effectively suppress the backscattering of electromag-netic waves in the 6～12 GHz band,achieving radar stealth,and the tunable range of infrared emissivity is approximately 0.25～0.45,enabling infrared camouflage.Additionally,the sample has good thermal in-sulation and flexibility,further expanding its application range.Moreover,the integrated design helps re-duce the structural thickness and processing complexity in engineering.In summary,this meta-surface de-sign holds promising application prospects in the fields of multi-spectrum compatible stealth and infrared camouflage.
