E-mail: lmis@miem.ru Theoretical and experimental results of temperature field distribution in sheet dielectric materials with waveguide type of electrodynamic system as heating element are presented. Analysis for waveguide type of electrodynamic system for the even thermal treatment of sheet materials is proposed. A kind of waveguide systems consists in changes according to the certain law of their wide walls along the lines of electromagnetic energy spreading. A method for waveguide wide walls geometric correction is suggested for the fundamental type of wave H10. Total divergence in theoretical and experimental results is less than 5% for the temperature field distribution in sheet materials with different electrophysical parameters.
