Split-Post Re-entrant Microwave Displacement Transducer with Quadratic Readout
Sonali Parashar, Jeremy F. Bourhill, Maxim Goryachev +1
We investigate a microwave-cavity-based displacement readout employing a split-post geometry to measure the motion of a dielectric membrane. Due to symmetry, the cavity response to…

Upconversion of Phonon Modes into Microwave Photons in a Lithium Niobate Bulk Acoustic Wave Resonator Coupled to a Microwave Cavity
S. Parashar, W. M. Campbell, J. Bourhill +3
The coupling between acoustic vibrations in a lithium niobate bulk acoustic wave resonator and microwave photons of a re-entrant microwave cavity was investigated at a temperature…

Low Temperature Properties of Low-Loss Macroscopic Lithium Niobate Bulk Acoustic Wave Resonators
William M. Campbell, Leonardo Mariana, Sonali Parashar +2
We investigate gram scale macroscopic bulk acoustic wave (BAW) resonators manufactured from plates of piezoelectric lithium niobate. The intrinsic competing loss mechanisms were st…
