The results of studies of solid-state materials using AMD-methods are presented. It is shown that, regardless of the type of structure of the studied materials and their nature, acoustic waves provide subsurface images. The proposed methods allow measuring the velocity of surface acoustic waves and their level of attenuation. These characteristics and acoustic images make it possible to evaluate the parameters of ordering the structure of subsurface layers of materials.

ABSTRACTIn this paper, we utilized a Stroh based formulation for solving problems of surface waves in layered piezoelectric media, and then, applied it to analyze surface acoustic wave (SAW) devices. The determination of the optimal cut of a piezoelectric crystal and the choice of the best propagation of SAW devices were given. The dispersion induced by a thin metal layer on SAW propagation in a SAW device was analyzed and discussed. Finally, we applied the formulation to calculate the effective permittivity and phase velocity dispersion of a LiNbO3/Diamond layered SAW device. Both of the null frequency bandwidth and the insertion loss of the dispersive SAW device were obtained.
