| Sumari: | Title screen An electrothermophysical model that makes it possible to estimate dielectric loss and predict energy-dissipation characteristics in dielectric materials is proposed. Heat and mass transfer is numerically simulated in the presence of microwave irradiation of an electronic device (polymer–semiconductor–composite system) with allowance for local heat liberation and nonlinear dependence of dielectric characteristics on temperature. Distributions of permittivity and tangent of dielectric loss with respect to thickness of the system under study are presented for a typical interval of variations in the parameters of electromagnetic radiation. It is demonstrated that dissipation of electromagnetic energy leads to a significant (by a factor of 1.6) increase in the tangent of dielectric loss.
