Abstract:
The propagation of anti-plane surface waves in an inhomogeneous magneto-electro-elastic MEE) half-space with 6mm symmetry is studied. By virtue of both direct and indirect methods, the dispersion relations corresponding to two general cases of material properties variation are obtained. In the first case, it is assumed that all material properties involving MEE properties and density vary similarly in depth. Whereas, the second case considers different variations for MEE properties and density. The non-dispersive shear surface wave velocities pertinent to homogeneous MEE media under eight different surface electromagnetic boundary conditions are obtained as the limiting cases of the current study. The dispersion curves corresponding to 11 inhomogeneity profiles of practical importance are presented in an effective dimensionless format, and the effects of inhomogeneity are discussed
