Effects of aspect ratio on the mode couplings of thin-film bulk acoustic wave resonators
We studied mode couplings in thin film bulk acoustic wave resonators of a piezoelectric film on a dielectric layer operating with the fundamental thickness-extensional mode. A system of plate equations derived in our previous paper was used which includes the couplings to the unwanted in-plane exten...
