The advent of transformation thermotics has seen a boom in development of thermal metamaterials with a variety of thermal functionalities, including phenomena such as thermal cloaking and camouflage. However, most thermal metamaterials-based camouflage devices only tune in-plane heat conduction, which may fail to conceal a target from out-of-plane detection. We propose an adaptive radiative thermal camouflage via tuning out-of-plane transient heat conduction, and it is validated by both simulation and experiment. The physics underlying the performance of our adaptive thermal camouflage is based on real-time synchronous heat conduction through the camouflage device and the background plate, respectively. The proposed concept and device represent a promising new approach to fabrication of conductive thermal metamaterials, providing a feasible and effective way to achieve adaptive thermal camouflage.

变形热学的出现见证了具有多种热功能的热超材料的发展热潮，包括热隐身和伪装等现象。然而，大多数基于热超材料的伪装装置仅调节面内热传导，这可能无法隐藏目标以防止面外检测。我们通过调整面外瞬态热传导提出了一种自适应辐射热伪装，并通过模拟和实验验证。我们的自适应热伪装性能背后的物理原理是基于分别通过伪装装置和背景板的实时同步热传导。所提出的概念和装置代表了一种有前途的制造导热超材料的新方法，
