Composite Piezoelectric Transducer

Application ID: 503

This example shows how to set up a piezoelectric transducer problem following the work of Y. Kagawa and T. Yamabuchi.

The composite piezoelectric ultrasonic transducer has a cylindrical geometry that consists of a piezoceramic layer, two aluminum layers, and two adhesive layers. The system applies an AC potential on the electrode surfaces of both sides of the piezoceramic layer.

The goal is to compute the admittance for a frequency range around the four lowest eigenfrequencies of the structure.

This is a benchmark model for ultrasonic transducer simulation but also a good starting point for simulations of SAW and BAW filters.

This model example illustrates applications of this type that would nominally be built using the following products:
