论文摘要
在两个远场分离的纳米颗粒之间的辐射热传递靠近完美导致的纳米线腐烂，对数衰变与颗粒间距离相对慢。这使气缸成为出色的波导，可以将热电磁能传递到任意大距离，而几乎没有损失。它导致热传递的急剧增加，因此，对于几乎任何（大）的分离，转移的能量可以与几百纳米分离的孤立颗粒一样大。现象学发现的分析公式准确地描述了广泛参数的数值结果。
Radiative heat transfer between two far-field-separated nanoparticles placed close to a perfectly conducting nanowire decays logarithmically slow with the interparticle distance. This makes a cylinder an excellent waveguide which can transfer thermal electromagnetic energy to arbitrary large distances with almost no loss. It leads to a dramatic increase of the heat transfer, so that, for almost any (large) separation, the transferred energy can be as large as for isolated particles separated by a few hundred nanometers. A phenomenologically found analytical formula accurately describes the numerical results over a wide range of parameters.
