In the past two decades, owing to the development of metamaterials and the theoretical tools of transformation optics and the scattering cancellation method, a plethora of unprecedented functional devices, especially invisibility cloaks, have been experimentally demonstrated in various fields, e.g., electromagnetics, acoustics, and thermodynamics. Since the first thermal cloak was theoretically reported in 2008 and experimentally demonstrated in 2012, great progress has been made in both theory and experiment. In this review, we report the recent advances in thermal cloaks, including the theoretical designs, experimental realizations, and potential applications. The three areas are classified according to the different mechanisms of heat transfer, namely, thermal conduction, thermal convection, and thermal radiation. We also provide an outlook toward the challenges and future directions in this fascinating area.
在过去二十年中，由于超材料的发展以及变换光学和散射消除方法的理论工具，大量前所未有的功能器件，尤其是隐形斗篷，已在电磁学、声学和热力学等各个领域通过实验得到了验证。自2008年首次从理论上报道热斗篷并于2012年通过实验验证以来，在理论和实验方面都取得了巨大进展。在这篇综述中，我们报告了热斗篷的最新进展，包括理论设计、实验实现和潜在应用。这三个领域是根据不同的热传递机制分类的，即热传导、热对流和热辐射。我们还对这个迷人领域中的挑战和未来方向进行了展望。
