MC simulation of radiative heat transfer between planar semi-infinite media and nano-spheres with near field effect

Based on the principle of electric dipole radiation and the Planck's spectral distribution of emissive power, the enhancement of thermal radiation between two planar semiinfinite media or two nano-spheres was studied in this paper by the Monte Carlo method. By this simple method, some parameter's influence on the radiative heat transfer was investigated, such as the distance between two semi-infinite media, the particle's radius, the distance between two particles and the difference in temperature between two particles, and so on. This solution is not rigorous but simple. The results show that heat transfer can be enhanced by several orders of magnitude for the near field effect. And the radiative heat transfer is decreasing sharply with the increasing of the distance.
