Abstract : A generator for variable frequency submillimeter waves launches surface acoustic waves in piezoelectric material for generation of an associated acousto-electrical field. an electron beam is acted upon by the acousto-electrical field in a manner simulating the effect of an etched grating, resulting in an output frequency which may be varied by the variation of the acoustic wave frequency, or the velocity of the electron beam.
