非互易表面波驱动的辐射热二极管

Radiative thermal diode driven by non-reciprocal surface waves

Annika Ott, Riccardo Messina, Philippe Ben-Abdallah, Svend-Age Biehs

摘要:

我们证明了通过将它们与Voigt配置中的磁光衬底的非互易表面模式耦合来校正两个纳米颗粒之间的纳米级辐射热通量的可能性。当非互易介质在发生热交换的光谱窗口中支持表面波时,整流系数可以达到很大的值,从而打开了真正的热二极管设计的道路。

英文摘要:

We demonstrate the possibility to rectify the nanoscale radiative heat flux between two nanoparticles by coupling them with the nonreciprocal surface modes of a magneto-optical substrate in a Voigt configuration. When the non-reciprocal medium supports a surface wave in the spectral window where heat exchanges take place the rectification coefficient can reach large values opening so the way to the design of true thermal diodes.
