Although the effective “stealth” of space vehicles is important, current camouflage designs are inadequate in meeting all application requirements. Here, a multilayer wavelength-selective emitter is demonstrated. It can realize visible light and dual-band mid-infrared camouflage with thermal control management in two application scenarios, with better effect and stronger radiation cooling capability, which can significantly improve the stealth and survivability of space vehicles in different environments. The selective emitter demonstrated in this paper has the advantages of simple structure, scalability, and ease of large-area fabrication, and has made a major breakthrough in driving multiband stealth technology from simulation research to physical verification and even practical application.

具有热管理功能的多波段伪装设计

尽管航天器的有效“隐身”很重要，但目前的伪装设计不足以满足所有应用要求。这里，展示了多层波长选择性发射器。可在两种应用场景下实现可见光和双波段中红外热控管理​​伪装，效果更好，辐射散热能力更强，可显着提高航天器在不同环境下的隐身性和生存能力。本文展示的选择性发射器具有结构简单、可扩展性强、易于大面积制造等优点，在推动多波段隐身技术从仿真研究到物理验证乃至实际应用方面取得了重大突破。
