Theoretical studies of wave propagation in multilayered piezoelectric media

摘要

The purpose of this paper is to extend the analysis of a single plate or substrate to the case of a multilayered medium. Due to the requiring of higher operating frequency, lower attenuation, and stronger piezoelectricity, layered structure becomes necessary. This technique is rapidly applied in the field of nondestructive evaluation and testing (NDE/T). Recently, a new feature of applying the piezoelectric effect for remote sensing, actuating, and vibration controlling came under study and development in aerospace and automative industries.
