Acoustic excitation of superharmonic capillary waves on a meniscus in a planar micro-geometry
arXiv:0912.2903 · doi:10.1063/1.2790968
Abstract
The effects of ultrasound on the dynamics of an air-water meniscus in a planar micro-geometry are investigated experimentally. The sonicated meniscus exhibits harmonic traveling waves or standing waves, the latter corresponding to a higher ultrasound level. Standing capillary waves with subharmonic and superharmonic frequencies are also observed, and are explained in the framework of parametric resonance theory, using the Mathieu equation.
