Heat treatment of sheet materials using slow-wave systems
The method of calculation of the temperature distribution in the dielectric material for the traveling wave microwave devices is presented. The basic equations for the temperature distribution in the direction of the electromagnetic field energy propagation with considering the dependence of the dielectric parameters of a material on the temperature changes and taking into account the heat transfer to the environment for the arbitrary design of the electrodynamic system are obtained. The results of calculation and measurements of the temperature distribution of the material in the direction of the traveling wave propagationat the electromagnetic field frequency oscillations of 2450 MHz are given. The discrepancy of calculated and measured characteristics of the temperature distribution in the material does not exceed 10%.
