Microwave heating and RF heating compared to the characteristics:
The following are the same as the "
So that the kinetic energy of electrons, into electromagnetic energy, accumulated in the resonant cavity, into the waveguide, and then into the application for use.
Microwave power source, the general use of magnetron for vibration, in the tube, the hot cathode electrons, in the strong constant magnetic field, the electrons for circular motion; magnetron internal resonator to slow down the electronic, so that
(3) the waveguide element and the applicator feed structure (4) sensing and controlling the four (4) the power supply (4)
Field can be converted into a high proportion of heat;
