Abstract
A method for heating a medium that includes an object having a variable weight is provided. The method comprises (A) placing medium including an object having variable weight into a variable enclosure having adjustable dimensions; (B) initiating a heating process by subjecting the medium including the object to a variable AC electrical field; (C) substantially continuously measuring an impedance of medium including the object during the heating process; (D) adjusting dimensions of said variable enclosure to optimize the heating process; (E) adjusting parameters of the variable AC electrical field to optimize the heating process; and (F) controlling the heating process.

A method for providing self-regulating capacitive electro-heating, said method comprising:
- (A) applying a single RF frequency Waveform power source to a capacitor coupled to said RF frequency Waveform power source, said capacitor including a variable enclosure;
- wherein a medium including an object having a variable weight is present in said variable enclosure and the single RF frequency is a frequency between 1 MHz and 250 MHz;
- (B) adjusting dimensions of said variable enclosure to maximize electric field capacitive coupling to the object and minimize capacitive coupling to empty space;
- (C) measuring an impedance of said variable enclosure including said object having variable weight;
- and
- (D) adjusting parameters of said RF frequency Waveform power source based on said measured impedance of said variable enclosure including said object having variable weight.
Apparatus for providing self-regulating capacitive electro-heating, said apparatus comprising:
- (A) means for applying a single RF frequency Waveform power source to a capacitor coupled to said RF frequency Waveform power source, said capacitor including a variable enclosure;
- wherein a medium including an object having a variable weight is present in said variable enclosure and the single RF frequency is a frequency between 1 MHz and 250 MHz;
- (B) means for adjusting dimensions of said variable enclosure to maximize electric field capacitive coupling to the object and minimize capacitive coupling to empty space;
- (C) means for measuring an impedance of said object having variable weight;
- and
- (D) means for adjusting parameters of said RF frequency Waveform power source based on said measured impedance of said object.
