Transverse Surface Waves in Piezoelectric Ceramic/Metal Coupled Media

摘要：

Theory of the propagation of transverse surface waves in piezoelectric ceramic/metal coupled media is developed. Dispersion equations relating phase velocity to material constants for the existence of various modes are obtained in simple mathematic form for a piezoelectric material of class 6mm. Piezoelectricity allows a nonleaky but dispersive wave of one or two modes to exist under conditions when the bulk-shearwave velocity in the layer is greater than that in the substrate. The study extends the regime of transverse surface waves and may lead to potential applications to acoustic wave devices.
