ABSTRACT:
A simplified method for fabricating composite transducers by bonding together plates of active and passive materials to form a laminated block. The active material is preferably a piezoelectric ceramic. Thereafter, a series of cuts are made in the laminated block to obtain a composite plate wherein regions of active material are separated from one another by regions of passive material. The method provides composite transducers having fine structures which can be produced without the difficulty of assembling many small rods or sawing deep, narrow grooves.
