摘要：
This paper presents the method to improve the performance of underwater transducers based on the porous piezoelectric ceramics. The Pareto-based approach has been used for the optimization of two types of devices: multilayered projector with an active layer made of porous piezoelectric ceramics and the membrane-type hydrophone with a perforated active piezoelectric diaphragm (pMUT). The simulations have been performed by means of the live-link of MATLAB and finite-element (FE) software Comsol Multiphysics. The numerical results are obtained and presented for both types of devices.
