Abstract : The patent describes a source of high frequency elastic waves generated by placing a Gunn effect oscillator in close proximity to a piezoelectric or an electrostrictive solid. The device creates a moving source of sound near the surface of the solid. The sould will be radiated from the surface of the solid as bulk or surface elastic waves. Elastic waves can be generated from both surfaces in certain situations.
