Resonant photon tunneling enhancement of the radiative heat transfer [PDF]

open access: yes, 2004
We study the dependence of the heat transfer between two semi-infinite solids on the dielectric properties of the bodies. We show that the heat transfer at short separation between the solids may increase by many order of magnitude when the surfaces are ...
