Extra two new piezoelectromagnetic SH-SAWs with dramatic dependence on small electromagnetic constant

It is expected that this theoretical report finalizes the research regarding to the shear-horizontal surface acoustic wave (SH-SAW) propagation along the suitable surface of the transversely isotropic (6 mm) piezoelectromagnetics. This report examines extra two new SH-SAWs, the existence of which dramatically depends on the small electromagnetic constant that is responsible for the magnetoelectric effect. This study also provides some comparison with the previously obtained theoretical results and the phenomenon called the Goldstone excitation. The obtained results can be useful for educational purposes, creation of novel technical devices based on the magnetoelectric effect that can find applications in spintronics, further theoretical treatments of the SH-wave propagation in plates, nondestructive testing and evaluation of apt surfaces and plates, etc.
