ABSTRACT:
An RF heating system for generating precision stray RF fields that can be used to heat materials. The RF heating system includes an RF power supply for generating RF signals and an electrode apparatus that is coupled to the RF power supply. An electrode apparatus according to the present invention has many advantages over existing electrode apparatuses. For example, the electrode apparatus is easier to manufacture, easier to duplicate, easier to control the manufacturing tolerances on the electrode system, and easier to correctly place and design the resulting RF stray field.
