Investigation goals- creating mathematical models of the heating process of boundered dielectics with losses and on this base to optimize the regimes of the microwave processing the humid materials. Investigation techniques- theoretical researches and computer analysis. Results of unvestigations. It is show that mathemetical model of forming the microwave power distribution, which are created on the base of solution of problem of the electromagnetic wave energy absorpion with the plane homogeneous layer of an anisotropic dielectric, is adequate to real pyshical prosesses. Electromagnetic power distributions heve been calculated for different radiating systems on the base of thin impedance vibrator: single, ortogonal and croseed vibrators over perfectly conducting plane screen and in the dielectric layer with losses between parallel perfectly conductiong plases. Itis shown that two-side irradiating the layer with cicrular polarized waves created with crossed vibrators provides more uniformity distribution of absorbed power. The problem of heating the half-space loss medium with the powerfull monochromatic electromagnetic wave was solved. Forms of dependences on the temperature ( i.e. on electromagnetic losees level in the medium) of thermo-and electrophysical parameters have been proposed, The influence of such dependencies on the absorbed microwave power in the medium and on its heating have been analyzed and calculated. The mathematical model of heating the plane layer of uniform absorptive dielectric with plane electromagnetic wave have been carried out. The model obtained allows to account processes which cause increasing or decreasing temperature ( absorption of electromagnetic power, evaporation, press and temperature of environment etc. ). Recommendations and technical proposals about improving the irradiating system of the work chamber of experimental microwave equipment have been formulated.
