Directional Characteristics of Slotted Piezoelectric Ceramic Tubes
Abstract
Single element and line transducers of various dimensions were fabricated from radially polarized, slotted piezoelectric ceramic tubes. The tubes exhibited multilobe directivity characteristics, in a plane normal to the axis of the tubes, at certain discrete frequencies. The shape of the directivity patterns are explained in terms of circumferential extensional vibrations with geometrically determined nodal positions. In addition, unidirectional response patterns were found at frequencies that were below the fundamental breathing mode of the tubes.
