Abstract

The propagation behavior of Love wave in functionally graded magneto-electro-elastic half-spaces with a quadratic variation is addressed. The coupling factor which is magneto-electromechanical, the dispersion relations, electrical as well as magnetic potential and displacement are provided in an analytical method in conditions that are the open and short electric magnet. Phase velocity, group velocity and magneto-electromechanical coupling factor are influenced by the gradient coefficient, and are estimated and discussed. Research on the wave propagation in magneto-electro-elastic materials is still very limited. This work provides us with a theoretical foundation to design and practically apply SAW devices with high performance.
