2. Basics of dielectric hysteresis processes
2.1 Electromagnetic wave-condensed matter interaction
The direct degradation of electromagnetic energy into heat within a dielectric material is possible as soon as a time-dependent electric field is applied to the material. In electrothermics, this is classically referred to as "heating by dielectric hysteresis". This hysteresis is strictly the electrical cause of energy degradation because, when the electrical stress ceases, i.e. when the applied electric field ceases or decreases, the dielectric polarization of the material does not instantly cancel or follow the decrease in the electric field. This delay...
