When two objects at different temperatures are separated by a vacuum gap they can exchange heat by radiation only. At large separation distances (far-field regime), the amount of transferred heat flux is limited by Stefan-Boltzmann's law (blackbody limit). In contrast, at subwavelength distances (near-field regime), this limit can be exceeded by orders of magnitude thanks to the contributions of evanescent waves. This article reviews the recent progress on the passive and active control of near-field radiative heat exchange in two- and many-body systems.
当两个处于不同温度的物体被一个真空间隙隔开时，它们只能通过辐射来交换热量。在较大的分离距离（远场 regime）下，传递的热通量受到斯特藩 - 玻尔兹曼定律（黑体极限）的限制。相比之下，在亚波长距离（近场 regime）下，由于倏逝波的贡献，这个极限可以被超越几个数量级。本文综述了在两体和多体系统中近场辐射热交换的被动和主动控制方面的最新进展。
