摘要：
热超材料代表了一种控制热传导的开创性方法，而作为关键组件，热隐形对热管理至关重要。尽管热隐形方案蓬勃发展，但在实际应用中仍面临两大局限。首先，物体通常被完全封闭在传统 cloak（斗篷）中，使其难以使用且不适用于带有热源的物体。其次，尽管已有理论提出通过改变材料的热导率来实现动态隐形，但其设计复杂且刚性，不适合在真实三维空间中大规模应用。在此，我们提出热力圆顶的概念以实现三维隐形。我们的方案包含一个开放功能区，极大提升了可用性与适用性。它具有可重构结构，由简单的各向同性天然材料构建，适用于动态需求。我们通过仿真和实验验证了该可重构热力圆顶的性能，结果与理论一致。这一概念的引入可极大推动热隐形技术从理论走向工程，并为直流电场和磁场等其他物理领域提供启发。
英文摘要：
Thermal metamaterial represents a groundbreaking approach to control heat conduction, and, as a crucial component, thermal invisibility is of utmost importance for heat management. Despite the flourishing development of thermal invisibility schemes, they still face two limitations in practical applications. First, objects are typically completely enclosed in traditional cloaks, making them difficult to use and unsuitable for objects with heat sources. Second, although some theoretical proposals have been put forth to change the thermal conductivity of materials to achieve dynamic invisibility, their designs are complex and rigid, making them unsuitable for large-scale use in real three-dimensional spaces. Here, we propose a concept of a thermal dome to achieve three-dimensional invisibility. Our scheme includes an open functional area, greatly enhancing its usability and applicability. It features a reconfigurable structure, constructed with simple isotropic natural materials, making it suitable for dynamic requirements. The performance of our reconfigurable thermal dome has been confirmed through simulations and experiments, consistent with the theory. The introduction of this concept can greatly advance the development of thermal invisibility technology from theory to engineering and provide inspiration for other physical domains, such as direct current electric fields and magnetic fields.
