ABSTRACT:
A microwave heating system utilizes a microwave energy generator to provide microwave energy through wave guides to targets. The targets are microwave absorbers and thereby increasing temperature upon the contact of microwave energy. The heated targets then transfer heat to an area to be heated such as by conduction, convection or radiation depending on the particular embodiment. A sensor in the area to be heated provides an input to a controller for controlling the input of microwave energy to be directed to the target.
