A two-dimensional theory based on the expansion of displacements in exact solutions from semi-infinite solids offers complete equations and boundary conditions for surface acoustic waves in finite elastic solids similar to well-known plate theories for high frequency vibration applications. By considering the electrode layer and discontinuous electrodes on an elastic substrate, the mass effect is evaluated through the integration of displacements along the thickness direction with simplified
