Energy flux of electromagnetic field in stochastic model of radiative heat transfer in dielectric solid medium

Abstract

The stochastic model that describes radiative heat tran sfe r in dielectric medium is analyzed. The model is based on the representation that heat tran sfer is realized both by its heat conductivity and by electromagnetic radiation th a t is generated by thermal fluctuations in the medium. Such physical suppositions, using fluctuation-dissipative theorem, are realized in the form of the infinite dimensional Ornstein-Uhlenbeck process that describes medium fluctuations
