In this paper, we study the transferred thermal radiation in a non-equilibrium but stationary system. Aforementioned system composed of a coated dielectric sphere that is assumed the spherical, shell and vacuum have different temperatures. For this purpose, we use the obtained relations from the canonical quantization of electromagnetic fields in the presence of medium for electric and magnetic fields and as well as the correlation function of their components. Then, by using the Green tensor of the aforementioned system, we compute the radial component of Poynting vector. Finally, the numerical calculation of exchange thermal radiation among these objects is calculated. 

Keywords: Radiative heat, Electromagnetic Green tensor, Propagating and evanescent waves
