Abstract: A method for assembling an ultrasonic transducer, first produces a plurality of plates of piezoelectric material. Then the plates are bonded together through use of a polymeric matrix comprising a polymer and intermixed particles having determined dimensional parameters, the particles acting to separate the plates by predetermined distances that are dependent upon the determined dimensional parameters. Preferred particles are polystyrene spheres. A second embodiment produces a plurality of strips of green piezoelectric ceramic material, each strip including a layer of a fugitive material. The strips are then placed in a stack and the stack is fired to convert the green piezoelectric ceramic material into densified ceramic plates. The firing acts to drive off said second fugitive material and to leave voids. The voids are then backfilled with a polymeric material to create a unified structure.
