文章亮点

(1) 归纳总结了实现非互易热超材料的不同方法

(2) 详细阐述了非互易热超材料（热传导和热辐射）的发展和应用前景

(3) 介绍了非互易超材料在其他拉普拉斯物理场中的应用

中文摘要

在天然材料中，由于受限于热流固有的各向同性扩散属性，难以实现非互易传热行为。而利用人工构建的热超材料，则可以打破系统互易性，实现对热流大小和方向的任意调控，在隔离保护、单向传输和能量收集等方面具有重要应用前景。本文首先从昂萨格互易定理出发，介绍了非互易热超材料设计的基本理论。其次，探讨了实现非互易传热的不同方法，包括使用非线性材料或结构、时空调制和引入角动量偏差等。进一步，讨论了实现非互易热辐射方面的实现方法。最后，介绍了非互易性在其他拉普拉斯物理场的潜在应用，并展望了非互易热超材料的未来研究方向。

Abstract

Abstract

Nonreciprocity of thermal metamaterials has significant application prospects in isolation protection, unidirectional transmission, and energy harvesting. However, due to the inherent isotropic diffusion law of heat flow, it is extremely difficult to achieve nonreciprocity of heat transfer. This review presents the recent developments in thermal nonreciprocity and explores the fundamental theories, which underpin the design of nonreciprocal thermal metamaterials, i.e., the Onsager reciprocity theorem. Next, three methods for achieving nonreciprocal metamaterials in the thermal field are elucidated, namely, nonlinearity, spatiotemporal modulation, and angular momentum bias, and the applications of nonreciprocal thermal metamaterials are outlined. We also discuss nonreciprocal thermal radiation. Moreover, the potential applications of nonreciprocity to other Laplacian physical fields are discussed. Finally, the prospects for advancing nonreciprocal thermal metamaterials are highlighted, including developments in device design and manufacturing techniques and machine learning-assisted material design.
