The continuation of our theoretical work on radiative heat transfer between parallel metal sheets has been published!
This work examines the competition between far field (traveling waves) and near field (evanescent waves) contributions to the heat current, revealing a key qualitative dependence on the 2D conductivity of the metal as compared to the speed of light.
In particular, we find that the physical mechanism behind the well-known effect heat transfer enhancement in the near field is different for poor and good conductors - (spoiler alert!) it is electrostatics and magnetostatics, respectively!

Now it's time to start writing the thesis...
