Abstract

An ultrasonic transducer usually consists of a piezoelectric element, an acoustic lens, matching layers and a backing materials. The foremost important issue in an ultrasonic transducer designing is the choice of the right materials. Therefore, determination of the bulk modulus B and the shear modulus (mu) in a broad megahertz frequency range for those materials is essential.
