Abstract:
A surface acoustic wave (SAW) device and it’s behavior at high frequencies is presented. The experiment and the simulations were done on ZnO film and with the software Comsol Multiphysics. The simulations helped us understand the potential distribution in ZnO with three different thicknesses: 150μm, 200μm and 300μm. Based on this results we plotted resonance frequencies for every thickness on a range from 1 Ghz up to 10 Ghz.
