Abstract: This theoretical report provides the supplemental theoretical results concerning the propagation of the shear-horizontal surface acoustic waves in the transversely isotropic piezoelectromagnetics (magnetoelectroelastic materials) of class 6mm. In this theory, the pure SH-waves are guided by the free surface of the bulk piezoelectromagnetic material. The following mechanical, electrical, and magnetic boundary conditions at the common interface between two continua such as a vacuum and the bulk material are employed in this study: the mechanically free surface, continuity of both the electrical and magnetic inductions, and continuity of both the electrical and magnetic potentials. Based on the natural coupling mechanisms such as e? ? h? and ?? ?? 2 in the coefficient of the magnetoelectromechanical coupling (CMEMC) it is argued that some additional new true solutions for the new surface SH-waves can exist. The existing incorrect solutions for this problem are also given and discussed. The obtained theoretical results can be useful for constitution of various technical devices based on smart magnetoelectroelastic materials and the further researches on the propagation of the interfacial SH-waves and the plate SH-waves in the piezoelectromagnetic (composite) materials.
