A furnace system for thermal processing of products and materials is disclosed which is particularly useful in processing touch screens for computer tablets and silicon wafers employed in fabricating solar cells. The system employs a hybrid of microwave and radiant heating of workpieces to provide controlled heating of the workpieces. A plurality of susceptors are disposed a furnace chamber. A plurality of microwave sources are arranged to provide microwave radiation in the chamber to uniformly heat workpieces in the chamber and to provide uniform heating of the susceptors. The susceptors are effective upon microwave heating by the microwave sources to provide uniform radiant heating of the workpieces in the chamber.

Furnace system having hybrid microwave and radiant heating

A microwave combustion system is presented that can replace the conventional spark plug in an internal combustion engine. One or more microwave pulses are provided to a microwave feed in a plug that sits in the cylinder. A microwave generated plasma generated by the plug in the vicinity of a fuel mixture can provide for highly efficient combustion of the fuel-air mixture.
