Abstract

Conventional single-band stealth systems face significant challenges in addressing multispectral detection technologies, necessitating urgent research into multi-band compatible stealth solutions. The study proposes and validates a novel visible-transparent microwave absorber with infrared shielding capability. The designed structure is composed of radar absorption layer (RAL) and an infrared shielding layer (IRSL). The RAL was designed using electromagnetic resonance principles and an equivalent impedance model, featuring a snowflake-inspired pattern with dual-level branching structures. The absorber achieves an absorption efficiency exceeding 90 % at frequencies above 9.25 GHz and an average visible light transmittance of 61.3 %. In addition, IRSL uses a frequency selective surface (FSS) with a hexagonal array design. It achieves high transmittance in the microwave band from 0 to 27 GHz and infrared emissivity as low as 0.32 in the 3–14 µm range. The designed absorber enables effective realization of radar-infrared compatible stealth, while maintaining visible light transparency that shows significant application potential in multi-spectrum compatible camouflage for optical windows and similar installations.

具有红外伪装和可见光透明的微波隐身超表面

传统的单波段隐身系统在处理多光谱探测技术方面面临重大挑战，迫切需要研究多波段兼容的隐身解决方案。提出并验证了一种具有红外屏蔽能力的新型可见透明微波吸收体。设计的结构由雷达吸收层（RAL）和红外屏蔽层（IRSL）组成。RAL采用电磁共振原理和等效阻抗模型设计，具有双层分支结构的雪花启发图案。该吸收器在9.25 GHz以上频率的吸收效率超过90%，平均可见光透过率为61.3%。此外，IRSL采用六边形阵列设计的频率选择表面（FSS）。在0 ~ 27 GHz微波波段具有高透射率，在3 ~ 14µm波段红外发射率低至0.32。设计的吸收器能够有效实现雷达-红外兼容隐身，同时保持可见光透明度，在光学窗口和类似装置的多光谱兼容伪装中显示出重要的应用潜力。

期刊介绍： The Journal covers the entire field of infrared physics and technology: theory, experiment, application, devices and instrumentation. Infrared'' is defined as covering the near, mid and far infrared (terahertz) regions from 0.75um (750nm) to 1mm (300GHz.) Submissions in the 300GHz to 100GHz region may be accepted at the editors discretion if their content is relevant to shorter wavelengths. Submissions must be primarily concerned with and directly relevant to this spectral region. Its core topics can be summarized as the generation, propagation and detection, of infrared radiation; the associated optics, materials and devices; and its use in all fields of science, industry, engineering and medicine. Infrared techniques occur in many different fields, notably spectroscopy and interferometry; material characterization and processing; atmospheric physics, astronomy and space research. Scientific aspects include lasers, quantum optics, quantum electronics, image processing and semiconductor physics. Some important applications are medical diagnostics and treatment, industrial inspection and environmental monitoring.
