本文利用精确散射矩阵（S矩阵）计算方法研究了多层双曲型异向介质的超普朗克近场热交换。我们研究了两个多层双曲型超材料结构之间的热交换。我们表明，这种超材料的超普朗克发射可以来自表面声子极化激元模式的存在下，或从双曲模式的连续取决于复合材料的选择以及结构配置。(C)2013年美国物理学会。[http：//dx.doi.org/10.1063/1.4800233]
We study super-Planckian near-field heat exchanges for multilayer hyperbolic metamaterials using exact scattering-matrix (S-matrix) calculations. We investigate heat exchanges between two multilayer hyperbolic metamaterial structures. We show that the super-Planckian emission of such metamaterials can either come from the presence of surface phonon-polariton modes or from a continuum of hyperbolic modes depending on the choice of composite materials as well as the structural configuration.
