ABSTRACT:
The present invention is a process for simulating a SAW device, while taking into account the thickness of the substrate. An aspect of the present invention is simulating a traveling surface acoustic wave in a periodic waveguide. The surface acoustic wave is simulated by analyzing an upper portion of the waveguide including a periodic array of electrodes using a periodic finite element method. The simulation further involves analyzing a lower portion of the waveguide including a bottom of the waveguide with an analytic method.
