The structure consists of layer and a semi-infinite medium. The layer is composed of a functionally graded magneto-electro-elastic material with a quadratic gradedness parameter. The semi-infinite medium is composed of functionally graded piezoelectric with a quadratic gradedness parameter. The interface between the layer and half-space is taken as loosely bonded and corrugated, whereas the upper boundary is assumed to be stress-free and corrugated. Moreover, the solutions for layer and half-space are obtained using the basic variable-separable method to reduce the partial differential equation to the ordinary differential equation. And ordinary differential equation solutions are obtained by using the WKB approximation technique. The solutions with boundary conditions lead to dispersion relations in the determinant form of two cases: electrically open and short. To know the impact of the parameter involved, a particular model consists of BaTiO<sub>3</sub>–CoFe<sub>2</sub>O<sub>4</sub> magneto-electro-elastic material layer and BaTiO<sub>3</sub> piezoelectric semi-infinite medium have been taken.
