In this study, a novel adaptive infrared (IR) camouflage film based on one-dimensional (1D) quasi-photonic crystal (PC) with phase-change material Ge₂Sb₂Te₅ (GST), is theoretically demonstrated. The designed film shows high emissivity state at low temperature and low emissivity state at high temperature, via the transition between amorphous and crystalline phase of GST. Moreover, the quasi-PC structure, designed with top optimized layers, possesses low emissivity property by splicing constructive interference (CI) peaks. In particular, the designed quasi-PC film is more conducive to the IR camouflage with variable object temperature (${\mathit{T}}_{\mathrm{o}}$), compared to those with static emissivity. This study provides a significant pathway to 1DPC application for adaptive IR camouflage and other technologies that rely on controlling the transfer of thermal radiation.

在这项研究中，从理论上证明了一种基于具有相变材料 Ge ₂ Sb ₂ Te ₅ (GST) 的一维 (1D) 准光子晶体 (PC) 的新型自适应红外 (IR) 伪装膜。通过 GST 的非晶相和结晶相之间的转变，设计的薄膜在低温下表现出高发射率状态，在高温下表现出低发射率状态。此外，采用顶部优化层设计的准 PC 结构通过拼接相长干涉 (CI) 峰具有低发射率特性。特别是所设计的准PC膜更有利于物体温度可变的红外伪装（${\mathit{吨}}_{\mathrm{○}}$)，与具有静态发射率的那些相比。这项研究为自适应红外伪装和其他依赖于控制热辐射传输的技术的 1DPC 应用提供了重要途径。
