Tunable and switchable film bulk acoustic resonators (FBARs) with the capability of dynamically adjusting their resonant frequencies hold significant promise for advanced multi-band radio frequency (RF) communication systems. However, tunable and switchable FBARs based on conventional thin ferroelec...
