DEFINITION

Classification: 264/417

Microwave (e.g., 2.45 gigahertz, etc.):

(under subclass 416) Processes in which the directly applied energy is identified on the electromagnetic wave spectrum as existing between far infrared and conventional radio-frequency.

(1) Note. A microwave is generally considered to be an electromagnetic wave which has a wavelength measured in the centimeter range. Microwaves occupy a region in the electromagnetic wave spectrum between infrared and radio-frequency. There are no distinct boundaries between these regions except by arbitrary definition.
