Focal sonic or ultrasonic radiator to apply to high-intensity fluids |
(57) The object of the present patent application is a new type of radiator for sonic
and/or ultrasonic frequencies consisting basically of a plate which has discontinuous
profiles on both surfaces and which vibrates flexurally on excitation by a vibrator
that may be piezoelectric, magnetostrictive, etc. in nature. The dual discontinuous
profiles enable regulation of the amplitude and phase of the energy radiated, thereby
achieving a high concentration of energy around a predetermined point.
