The existing challenges in designing infrared illusion are related to complex working environments, multifold heat-transfer modes, and fabrication difficulties. Recent research focuses mainly on solving one of these challenges. In this work, we consider them synthetically and propose a class of restructurable metasurfaces to show both illusion viewed in infrared light and similarity in when viewed in visible light. We consider the three basic modes of heat transfer (omnithermotics) in theoretical designs and use radiation-cavity effects in experimental manufacture. We also make it feasible to tune the surface temperature and emissivity synergistically. Besides, such metasurfaces can work in temperature-varying backgrounds and transient states. This scheme may not only provide a platform for the design of adaptable thermal illusion but may also show robustness under multifrequency detection.

红外幻觉和可见光相似性的全热可重构超表面

设计红外错觉的现有挑战与复杂的工作环境，多种传热模式和制造困难有关。最近的研究主要集中在解决这些挑战之一。在这项工作中，我们综合考虑它们，并提出了一类可重构的超表面，以显示在红外光下看到的幻觉和在可见光下看到的相似性。我们在理论设计中考虑了传热（全热）的三种基本模式，并在实验制造中使用了辐射腔效应。我们还可以协同调整表面温度和发射率。此外，这样的超表面可以在温度变化的背景和瞬态中工作。
