Abstract

We propose a mathematical model for the simulation of surface acoustic wave (SAW) devices. The model describes the propagation of waves in a unit cell of a periodic structure and uses the finite element method (FEM) approach along with the perfectly matched layer (PML) technique. The periodicity is treated by means of the method of Lagrange multipliers. Numerical results demonstrate the accuracy and the applicability of the developed computational scheme.
