Bulk acoustic resonators—stacked material structures inside which acoustic waves resonate—can be used to amplify sounds or filter out undesired noise. These resonators have found wide use in today’s RF telecommunication, like Front-End Modules (FEM) in iPhones. They could also be valuable components for various cutting-edge scientific applications, including quantum technologies and imaging devices.
