Abstract: The finite-difference time-domain (FDTD) technique is, for the first time, extended to analyze the frequency response of surface acoustic wave (SAW) filters. In this method, the partial derivatives of quasi-static Maxwell's equations and equation of motion are discretized to centered finite-differences. In addition, the perfectly matched layer (PML) boundary condition is applied to reduce the spurious reflections. The model is applied to analyze the influence of the number of electrodes on the frequency response of a SAW filter fabricated on a zinc oxide (ZnO) substrate.
