Description of the surface radiation of non-equilibrium media using transfer function

Abstract

The paper justifies the possibility of applying the concepts of transfer function to the description of the radiation of non-equilibrium media surface. Fourier optics terms allow you to reason about the comparison of perturbations magnitudes. These perturbations are inherent in the non-equilibrium radiating surfaces. As a comparison, the magnitudes that actually characterize elementary radiators are used. This conclusion can be applied to smooth surfaces of arbitrarily complex shape.
