  The study of this theoretical work definitely adds extra four new dispersive
shear-horizontal waves propagating in the transversely isotropic
piezoelectromagnetic (PEM) plates of class 6 mm. In this study, the following
mechanical, electrical, and magnetic boundary conditions at both the upper and
lower free surfaces of the PEM plate are exploited: the mechanically free
surface, continuity of both the electrical and magnetic inductions, and
continuity of both the electrical and magnetic potentials. The obtained
dispersion relations were also graphically studied and compared with previous
results. Some interesting peculiarities were also discussed. It is well-known
that the plate waves are frequently used for nondestructive testing and
evaluation of thin films, further miniaturization of different technical
devices based on PEM smart materials, and constitution of new technical devices
such as filters, sensors, delay lines, switches, lab-on-a-chip, etc.
