The microwaves used for practical heating applications are typically electromagnetic waves having frequencies of 915MHz and 450 MHz. The simple principle of microwave heating is that the polarization of the alternating electromagnetic field rearranges the free charges in the material and the dipoles are repeatedly adjusted and rotated, so as to generate strong vibration and friction, and the energy of the alternating electromagnetic field is converted into heat energy in the medium in the microscopic process, so that the temperature of the medium is increased, and therefore, the microwave heating is that the medium material loses the energy of the electromagnetic field to generate heat, and essentially belongs to an internal heating mode.
