Influence of corrugation on SH wave propagation in rotating and initially stressed functionally graded magneto-electro-elastic substrate

The shear horizontal (SH) waves in a rotating system comprising an initially stressed magneto-electro-elastic substrate were studied analytically. The upper boundary of substrate is taken as corrugated and stress free. With respect to electrically and magnetically upper boundary considered as two cases electrically and magnetically open and electrically and magnetically short. Dispersion equations have been obtained for electrically open and magnetically open and also electrically and magnetically short situations with corrugated interface. Based on the numerical results, the properties of SH waves through the proposed framework and the conditions depending on various physical and geometrical parameters have been examined. The study examines the simultaneous simulated results of several physical parameters, including rotation, inhomogeneity, phase velocity, initial stress, and corrugated SH wave interface distribution in the structure under consideration, which were created using Mathematica 7. The examined model could be helpful for the development of surface acoustic wave (SAW) devices.
