Laser-interferometric analysis of surface acoustic wave resonators [PDF]

, 2005
The research work described in this Thesis concentrates on studying surface acoustic wave (SAW) resonators, in particular resonators which utilize the leaky surface acoustic wave (LSAW) mode. Such resonators constitute building blocks for radio-frequency

Effects of geometry on quantum fluctuations of phonon-trapping acoustic cavities

New Journal of Physics, 2014
This work presents some peculiarities of the near quantum ground state behaviour of curved (phonon trapping) bulk acoustic wave (BAW) cavities when compared to a conventional mechanical resonator.

Thin Film Piezomaterials for Bulk Acoustic Wave Technology

, 2015
In the first edition of "The Nano-Micro Interface," we discussed the piezoelectric quality of zinc oxide (ZnO) thin films. In this second edition's chapter, we have extended our view and included other piezoelectric materials like AlN, Sc-alloyed AlN ...

Upconversion of phonon modes into microwave photons in a lithium niobate bulk acoustic wave resonator coupled to a microwave cavity

APL Photonics
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 close to 4 K.

Enhanced Acoustic Mixing in Silicon-Based Chips with Sharp-Edged Micro-Structures

Micro
The small dimensions of microfluidic channels allow for fast diffusive or passive mixing, which is beneficial for time-sensitive applications such as chemical reactions, biological assays, and the transport of to-be-detected species to sensors.

Characterizing Acoustic Behavior of Silicon Microchannels Separated by a Porous Wall

Micromachines
Lateral flow membrane microdevices are widely used for chromatographic separation processes and diagnostics. The separation performance of microfluidic lateral membrane devices is determined by mass transfer limitations in the membrane, and in the liquid

Legendre polynomial modeling of composite bulk acoustic wave resonators

, 2008
The Legendre polynomial method has been extended to the modeling of bulk acoustic wave (BAW) resonators. Modifications have been made to the formulation in order to account for large differences in the physical properties of adjoining layers and to take ...
