| Popis: |
Radial mechanical modes of miniature disk-shaped resonators are promising candidates for probing the ultra-high-frequency rheological properties of liquids. However, the lack of an analytical fluid-structure model hinders the inference of liquid properties from the experimental measurement of such radial vibrations. Here we develop analytical models for the case of a disk vibrating in a compressible viscous liquid. Closed-form expressions for the mechanical quality factor and resonant frequency shift upon immersion are obtained, which we compare to the results of numerical modeling for a few significant cases. At frequencies above 1 GHz, our model points out the significance of compressibility effects. |
