Abstract:
1. A method for heating an object having a variable weight that includes a medium, said method comprising: placing said object including said medium into an enclosure comprising a rotating drum having at least one anode element and at least one cathode area: wherein said object absorbs said medium in a first “cool” state, and said object includes a maximum weight in said first “cool” state due to absorption of said medium; initiating a heating process by capacitively coupling said object to an AC electrical field originated from an RF power source; wherein said object including said medium transitions into a second “heated” state in which there is less medium than in said “cool” state due to release of said medium from said object; and controlling said heating process by taking real time measurements and by controlling RF parameters in real time based upon said measurements; wherein: said heating process is completed when said object is transitioned into said second “heated” state; and said parameters are selected from the group of parameters consisting of an RF voltage magnitude and envelope wave shape, an applied RF current magnitude and envelope wave shape, phase of RF voltage versus current, and voltage standing wave ration.
