Analytical Investigation of Surface Wave Characteristics of Piezoelectromagnetics of Class 6 mm

Abstract EN

This short work copes with theoretical investigations of some surface wave characteristics for transversely isotropic piezoelectromagnetic composites of class 6 mm.

In the composite materials, the surface Bleustein-Gulyaev-Melkumyan wave and some new shear-horizontal surface acoustic waves (SH-SAWs) recently discovered by the author can propagate.

The phase velocities Vph of the SH-SAWs can have complicated dependencies on the coefficient of the magnetoelectromechanical coupling Kem2 (CMEMC) which depends on the electromagnetic constant α of the composites.

Therefore, the analytical finding of the first and second partial derivatives of the Vph(α) represents the main purpose of this study.

It is thought that the results of this short letter can help for theoreticians and experimentalists working in the research arena of opto-acoustoelectronics to completely understand some problems of surface wave propagation in piezoelectromagnetics.
