超普朗克远场辐射的等效电路分析
Equivalent Circuit Analysis of Super-Planckian Emission into Far Field
摘要：
使用我们最近开发的等效电路模型的辐射热传递，我们分析了远场热发射的约束尺寸的机构。我们证明了一个假设的超材料发射器，这是共轭匹配的所有谐波的发射场在给定的波长辐射的功率可以无限高于由相同半径的理想黑体发射的功率。然而，对于光学大物体，满足高阶谐波的共轭匹配条件并不是一项微不足道的任务，这有效地限制了远场辐射功率由众所周知的普朗克定律。
英文摘要：
Using our recently developed equivalent circuit model of radiative heat transfer we analyze the far-field thermal emission from bodies of constrained dimensions. We prove that the power radiated by a hypothetical metamaterial emitter which is conjugate matched with all the harmonics of the emitted field at a given wavelength can be infinitely higher than the power emitted by an ideal black body of the same radius. However, for optically large bodies, fulfilling the conjugate match conditions for higher-order harmonics is not a trivial task, which effectively limits the far-field radiated power by the well-known Planck law.
