Propagation of SH-Wave in a Rotating Functionally Graded Magneto-Electro-Elastic Structure with Corrugated Interface

Abstract

The SH waves in a rotating functionally graded system comprising an elastic substrate and functionally graded magneto-electro-elastic layer are studied analytically. The bonding of layer and substrate are well contact with corrugation as well as upper boundary taken as corrugated with stress free. Dispersion relations have been obtained for four cases of electrically open and magnetically open, electrically short and magnetically short, electrically open and magnetically short, and electrically short and magnetically open 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 inhomogeneity, layer thickness, rotation, and amplitudes of corrugation, which were created using Mathematica 7. The examined model could be helpful for the development of surface acoustic wave (SAW) devices.
