Simulation and experimental verification of the acoustic field produced by an annular piezoelectric array

In the field of ultrasound transducers to generate frozen rings waves generated a tendency for use in biomedical applications. This paper proposes simulate through Finite Element Method (FEM) simulation of a transducer with 10 rings to find patterns of acoustic field and get a model attached to the real transducer designed by Castellanos et al [3]. This work focuses on obtained results of acoustic field as close as possible to those real measurements, with all this process entails: geometry, the definition of materials piezoelectric, the FEM equations governing the physics of problem and the resolution of the mesh. Whereby are obtained results showing patterns similar to those obtained in the real acoustic field measurements, in order to propose to extend this work to find the combination of this transducer modeling using the FEM.
