DEFINITION

Classification: 438/777

Microwave gas energizing:

(under subclass 776) Processes wherein the irradiation is of microwave frequency.

(1) Note. The FCC allowed frequency for microwave energy is 2.45 GHz, with a corresponding wavelength of from 1mm to 1m.

(2) Note. Microwave is a term applied to electromagnetic waves which occupy a region in the electromagnetic spectrum which is bounded by radio waves on the side of longer wavelengths and by infrared waves on the side of shorter wavelengths.
