This theoretical work demonstrates the existence of seven new shear-horizontal surface acoustic waves (SH-SAWs) when different electrical and magnetic boundary conditions are applied. All the discovered SH-SAWs can propagate on the surface of the cubic piezoelectromagnetics along direction [101]. Calculations of the new SH-SAW features were performed for two-phase composites with the piezomagnetic phase (Metglas, Terfenol-D, Galfenol, Alfenol) and the piezoelectric phase (Tl3TaSe4, Tl3VS4, PZT). It was also found that the surface Bleustein-Gulyaev-Melkumyan wave can propagate in the cubic...

This theoretical work has the purpose to thoroughly investigate the problems of shear-horizontal (SH) interfacial acoustic wave propagation guided by the common interface between two dissimilar piezoelectromagnetic hexagonal half-spaces of class 6 mm. At the interface, the mechanical, electrical, and magnetic boundary conditions can support the interfacial SH-wave propagation. The equality of the mechanical displacements and the normal components of the stress tensor (mechanically free interface) were used as the mechanical boundary conditions. The electrical and magnetic boundary conditions...
