Controlling thermal emission plays a vital role in various applications. Existing control of thermal emissions have been limited to simple functions such as directional and spectral selectivity. Complex control of thermal emission remains underexplored. Here, we show a new type of thermal emitters with mesoscopic structures. These emitters have sizes in the range of tens to hundreds of wavelengths. The wave effects of emitted thermal photons enable complex control of thermal emission through optical coupling. These emitters can exhibit phenomena such as self-focused emission and thermal holograph. A new theoretical framework is introduced to describe rich wave dynamics in mesoscopic thermal emitters. It accurately accounts for both the wave dynamics in electrically large structures and the statistical fluctuation of thermal emission.

介观热发射器实现的自聚焦热发射和全息照相

控制热辐射在各种应用中起着至关重要的作用。现有的热辐射控制仅限于简单的功能，例如方向性和光谱选择性。对热辐射的复杂控制仍未开发。在这里，我们展示了一种具有介观结构的新型热辐射器。这些发射器的大小在数十到数百个波长范围内。发射的热光子的波效应使得可以通过光学耦合复杂地控制热发射。这些发射器会表现出诸如自聚焦发射和热全息图等现象。引入了一个新的理论框架来描述介观热辐射体中的丰富波动力学。它可以准确地解释大型电气结构中的波浪动力学以及热辐射的统计波动。
