We develop a dipole model describing the thermal far-field radiation of a nanoparticle in close vicinity to a substrate. By including in our description the contribution of eddy currents and the possibility to choose different temperatures for the nanoparticle, the substrate, and the background, we generalize the existing models. We discuss the impact of the different temperatures, particle size, emission angle, and the distance dependence for all four combinations of gold and SiC nanoparticles or substrates.

偶极子模型，用于在平面基板上方进行纳米粒子的远场热发射

我们开发了一个偶极子模型，该模型描述了紧邻基底的纳米粒子的热远场辐射。通过在我们的描述中包括涡流的贡献以及为纳米粒子，基底和背景选择不同温度的可能性，我们可以对现有模型进行概括。我们讨论了金和SiC纳米颗粒或基材的所有四种组合的不同温度，粒径，发射角和距离相关性的影响。
