ABSTRACT:
A dielectric layer is located between two capacitor electrodes and is heated by a radio frequency transmitted from a radio frequency generator. In order to conduct a high energy from the generator into the load, a coaxial line having a length which corresponds to 1/4 of the wavelength of the desired frequency is utilized and its characteristic impedance is formed from the geometrical mean of real load resistance and optimum working resistance of the generator.
