Abstract

The analysis of surface acoustic waves in finite elastic solids is of fundamental and practical importance, giving the fact that those typical problems concerning solutions of the well-known wave propagation equations are hard to obtain. In searching of an accurate analytical method, we compare this problem with the known bulk acoustic wave problems in finite plates and corresponding Mindlin and Lee plate theories which have been instrumental in solving these problems with accuracy and simplicity. Analogous to power and trigonometric series expansions of displacements, we use exponential functions obtained from semi-infinite solutions of surface acoustic waves to represent the decaying displacements along thickness direction. We present a two-dimensional theory specifically for surface acoustic waves in finite solids with goals to use it for surface acoustic wave resonator analysis and design. The two-dimensional theory for piezoelectric plates is presented and considered through the effective elastic constants for simplification.
