Abstract
The application of advanced detection technologies has made single-band camouflage materials ineffective. Therefore, it is necessary to develop infrared multi-band camouflage technology. Here, we propose a design method that combines genetic algorithm (GA) and rigorous coupled-wave analysis (RCWA) to achieve compatible camouflage across visible, near-infrared laser, and mid-infrared bands for a multilayer structure. By precisely controlling the thickness of the top layer material, this structure can exhibit different colors within the visible light band, thereby achieving a camouflage effect in the visible light band. Besides, the structure has high absorption in the laser band (α1.06 μm = 0.91, α1.55 μm = 0.99, α10.6 μm = 0.98), low emissivity in the infrared bands(α3-5μm = 0.29, α8-14μm = 0.29). The relatively high average emissivity in the non-atmospheric double-window band (ε2.5–3 μm = 0.41, ε5-8μm = 0.78) facilitate effective heat dissipation. This research provides a method for designing multi-spectral compatible camouflage technology which holds potential application value in military fields.
期刊介绍:
Optics Communications invites original and timely contributions containing new results in various fields of optics and photonics. The journal considers theoretical and experimental research in areas ranging from the fundamental properties of light to technological applications. Topics covered include classical and quantum optics, optical physics and light-matter interactions, lasers, imaging, guided-wave optics and optical information processing. Manuscripts should offer clear evidence of novelty and significance. Papers concentrating on mathematical and computational issues, with limited connection to optics, are not suitable for publication in the Journal. Similarly, small technical advances, or papers concerned only with engineering applications or issues of materials science fall outside the journal scope.
