THE DEVELOPMENT AND APPLICATION OF THE TECHNIQUE OF CALCULATION OF THERMAL BREAKDOWN VOLTAGE IN THE HIGH-FREQUENCY STRUCTURES

: The paper deals with the description of a new technique of calculations of the heat release processes at the high and ultra-high frequencies associated with the losses in composite materials (CM) what may cause the destruction of radio components. The study of thermal breakdown is necessary to determine the mechanism and nature of change of dielectric properties. Thermal breakdown influences destructively the composite material radio components or even causes their failure. The heating phenomena are rather complex and the calculation of its origination mechanism, as well as the stages of the origination and development of thermal effect and composite material aging, are scientifically and practi-cally attractive.
