Abstract: One of the possible ways to further miniaturize technical devices is the utilization of the two-dimensional structures such as plates. The acoustic wave propagation is one of the important characteristics. This theoretical work provides two new shear-horizontal (SH) dispersive acoustic waves. The SH-wave dispersion relations are obtained in explicit forms for the case of the transversely isotropic (6 mm) plates. In the plate, the propagation of either new SH-wave is coupled with the electrical, magnetic, gravitational, and cogravitational potentials. Using the obtained SH-waves, it is possible to constitute various technical devices (filters, sensors, etc.) of acoustoelectronics and spintronics, and to integrate them in the new communication era based on some gravitational phenomena. Also, the plate SH-waves are apt for nondestructive testing and evaluation of (composite) thin films.
