General formulation of coupled radiative and conductive heat transfer between compact bodies

We present a general framework for studying strongly coupled radiative and conductive heat transfer between arbitrarily shaped bodies separated by subwavelength distances. Our formulation is based on a macroscopic approach that couples our recent fluctuating volume-current (FVC) method of near-field heat transfer to the more well-known Fourier conduction transport equation, in which case the former can induce temperature gradients throughout the...
