The chapter is devoted to modeling of non-uniformly polarized piezoelectric devices. We suggest that applying specific types of preliminary polarization can lead to significant growth of the electroelastic parameters of the device. Such parameters are electro-mechanical coupling coefficient, bandwidth of the transducer, maximum output voltage in circuit with resistor, eigen frequencies. Different approaches to modeling were tested and compared during study, including finite-element method in different packages and applied theory based on known plate models. © 2017, Springer International Publishing AG.
