Entropy density and entropy flux in near-field thermal radiation
arXiv:1210.7607 · doi:10.1103/PhysRevB.88.075412
Abstract
We propose a method to evaluate the entropy density and entropy flux in a vacuum gap between two half-spaces that takes into account influence of near-field effects, i.e., interference, diffraction, and tunneling of waves. The method developed is used to determine the maximum work that can be extracted through near-field radiative transfer between two half-spaces at different temperatures.
