Simulation of heating dielectric media by electromagnetic radiation in nonlinear mode

Abstract

Under study is the process of heating a moving medium by high-frequency electromagnetic radiation in presence of heat exchange with the environment, in the approximation of a thermally thin layer. It is shown that, due to the competitive nature of the processes of heat emission in the heated media and heat exchange with the environment, the temperature profiles are realized in the form of autowaves. Inspecting analytical and numerical solutions, we determine the basic regularities of the dynamics of temperature waves.
