Abstract
A solid-state heating apparatus may be incorporated into stand-alone appliances or other systems. The heating apparatus may include an impedance matching network coupled between an electrode and a radio-frequency (RF) source. The impedance matching network may be a variable impedance matching network that can be adjusted during the heating operation. The impedance matching network may include planar inductors formed from patterned conductive layers disposed either side of a substrate.
