Abstract

Infrared detection is promising for aircraft surveillance. The stealth aircraft displays intense radiation characteristics in the two long-wave infrared frequency ranges (8.02-

$8.58~\mu $

m and 9.24-

$9.96~\mu $

m). Therefore, it is quite important to enhance the detection precision in these two ranges. In addition, camouflage of the infrared detector itself requires low emissivity in the long-wave-infrared range. Moreover, in order to cool down the infrared detector, it is desirable to increase emissivity in the 5-

$8~\mu $

m non-atmospheric window. In this work, a multifunctional metasurface with the Au/SiO2/Au thin film structure is designed and prepared. The structure exhibits high emissivity of 0.65 and 0.72 in the aircraft detection windows (8.02-

$8.58~\mu $

m and 9.24-

$9.96~\mu $

m) while maintaining low emissivity of 0.23 outside the detection windows for IR stealth. It also achieves high emissivity, with a maximum value of 0.65 and an average value of 0.38, in the non-atmospheric window (5-

$8~\mu $

m) for thermal management. Exploration in the physical mechanisms of the compatible metasurface is conducted and discussed that the periodic array metal structure at the top layer allows the frequency selectivity while the metal/insulator/metal (MIM) structure localizes the incident wave under the synergistic effect of the intrinsic properties of materials and local surface plasmon, resulting in resistance losses. This work might bring more opportunities in military fields for optimizing multispectral infrared detection, device camouflage and radiation transmission signal processing.

期刊介绍： IEEE Photonics Technology Letters addresses all aspects of the IEEE Photonics Society Constitutional Field of Interest with emphasis on photonic/lightwave components and applications, laser physics and systems and laser/electro-optics technology. Examples of subject areas for the above areas of concentration are integrated optic and optoelectronic devices, high-power laser arrays (e.g. diode, CO2), free electron lasers, solid, state lasers, laser materials'' interactions and femtosecond laser techniques. The letters journal publishes engineering, applied physics and physics oriented papers. Emphasis is on rapid publication of timely manuscripts. A goal is to provide a focal point of quality engineering-oriented papers in the electro-optics field not found in other rapid-publication journals.
