ABSTRACT
Radiative heat transfer is the mode of energy transport in which electromagnetic waves of the thermal range carry energy and convert it to heat while they interact with surfaces or media. An ideal emitter is one that emits the maximum possible radiation at a given temperature and is called a blackbody. The microscopic approach to obtain the radiative heat transfer involves the use of the concept of photons, which carry quanta of energy, and the summation of all quantized energy transport over the number of photons. Various temporal microscales have been defined, with reference to short pulse lasers propagating through media. Modern trends in microminiaturization have made the analysis of radiative phenomena in the microscale very important. The effects of the interference of waves are neglected in conventional modeling of radiation propagation through particulate systems, assuming independent absorption and scattering of radiation by the particles.
