Abstract :
The equivalent circuit model of piezoelectric ceramic pillar transducer with matching layer material is proposed, and the applicability of this model in the U-shape transducer array is discussed. The vibration character and directivity pattern of the transducer are analyzed by the finite element method. The manufactured U-shape transducer array has verified feasibility of the piezoelectric ceramic pillar transducer with matching layer design. The broadband and high power density characters of such design are suitable for high frequency broadband acoustic emission with special directivity.
