Latest Patents

Xu Han's latest patents focus on an innovative acoustic resonator. This resonator features a piezoelectric stack that includes a piezoelectric layer with a top and bottom surface. It is equipped with a top electrode layer positioned above the top surface and a bottom electrode layer located beneath the bottom surface. The design incorporates several acoustic wave reflectors on the side of the bottom electrode layer that is opposite the piezoelectric layer. Each reflector consists of a high acoustic impedance layer and may also include a low acoustic impedance layer. Additionally, the acoustic resonator is designed with a tether that extends laterally to the stacking direction of the piezoelectric layers. A supporting structure is coupled to the tether, which anchors the resonator. To prevent resonant waves from escaping during operation, a mirror, one or more phononic crystals, or both may be positioned near the tether opposite the acoustic resonator.
