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.
