TL;DR: In this article, a general formalism is developed by means of which the radiative heat transfer between macroscopic bodies of arbitrary dispersive and absorptive dielectric properties can be evaluated.
Abstract: A general formalism is developed by means of which the radiative heat transfer between macroscopic bodies of arbitrary dispersive and absorptive dielectric properties can be evaluated. The general formalism is applied to the heat transfer across a vacuum gap between two identical semi-infinite bodies at different temperatures. The peculiarities arising when the gap width is of the order of, or smaller than, the dominant thermal radiation wavelengths are studied and quantitatively evaluated for the case of two metal bodies. The predicted strong increase with diminishing gap width is in qualitative agreement with experimental results.

TL;DR: In this article, the basics of thermal radiation necessary for the thermal modelling of spacecraft are presented, and the equations necessary to determine the radiation exchange between diffuse, grey surfaces are obtained and written in terms of thermal resistances to apply the electrical analogy.
Abstract: This chapter presents the basics of thermal radiation necessary for the thermal modelling of spacecraft. The nature of thermal radiation is briefly described while the concept of blackbody and the Planck’s distribution, describing the spectral emissive power of a blackbody, are presented. The thermo-optical properties of a surface, emissivity, absorptance, transmittance and reflectance, are defined, and the equations necessary to determine the radiation exchange between diffuse, grey surfaces are obtained and written in terms of thermal resistances to apply the electrical analogy.
