Abstract :
Two, 1-dimensional piezoelectric transducer models are presented that use complex numbers to represent mechanical and dielectric loss. Exact numerical agreement was achieved by avoiding a number of small errors in the literature. A correction to Kino´s (1987) simplified Mason parallel equivalent circuit is also given. Efficiency is discussed.
