Abstract

Electromagnetic lead magnesium niobate ceramics (PMN) are promising materials for realizing actuators or high power transducers for macrosonics or underwater acoustics. The use of PMN as active material in actuators and transducers presents some difficulties which include: highly nonlinear properties; temperature and frequency dependence of dielectric permittivity; and the need for direct current bias field. To help in the design of PMN-based transducers, a numerical modeling capability and a FEM are needed.
