Heating can occur through conduction and the species (particles or carriers) in the material must be free to move and promote the induction of a current. However, if charged species present a certain resistance to movement, which can occur due to geometric factors, these charges will move until an opposing force counterbalance them. This results in the establishment of a dielectric polarization. Thus, we observe that the effects of microwave heating result in both conduction and dielectric polarization .
