摘要

The SH wave propagates through a functionally graded magneto-electro-elastic substrate, and this study investigates its propagation characteristics. The imperfections at the substrate-vacuum interface include various shapes and geometries commonly associated with both electrically open and magnetically open and electrically short and magnetically short cases. The research analyzes the combined effects of irregularities, depth sources, and inhomogeneity. Using Fourier transforms, the results are validated against solutions for simpler layered systems, highlighting key findings. A particular BaTiO3-CoFe2O4 magneto-electroelastic material model is utilized to analyze the influence of the associated parameters. Mathematica 7 was used to generate graphs illustrating the results, displaying changes in wavenumber and phase velocity.
