INFLUENCE OF MICROWAVES ON THE THERMAL CONDITIONS OF A "POLYMER–SEMICONDUCTOR–COMPOSITE" SYSTEM

A numerical analysis of the influence of microwaves on the thermal conditions of elements of electronic equipment (EE) has been carried out. Investigations have shown that the temperature fi eld of the ″polymer–semiconductor– composite″ system under the action of microwaves is nonuniform. It has been established that under rather typical operating conditions with increasing electric fi eld intensity there is a considerable increase (from 362 to 387 K) in the maximum temperature of the modeled object. Such a strong infl uence of microwaves on the thermal conditions of the ″polymer–semiconductor–composite″ system is comparable to the increase in the ambient temperature by 20 K or the increase in the heat release of the internal source by 30%.
