摘要

铁电陶瓷和晶体是许多基于压电效应的声换能器的主要组成部分。这些材料表现出不同类型的损耗(介电、机械或耦合、压电“损耗”)，这可能对其阻抗的共振产生强烈影响。

Modeling losses of a piezoelectric resonator: Analytical vs finite elements analysis

Ferroelectric ceramics and crystals are the main component of many acoustic transducers based on piezoelectric effect. These materials exhibit different types of losses (dielectric, mechanical or coupled, piezoelectric “losses”) which may have strong effect on the resonances of its impedance.
