Axisymmetric gravity-capillary standing waves on the surface of a fluid

We conduct an experimental study of axisymmetric gravity-capillary standing waves generated by a vertically vibrating ring on fluid surface. Different regimes are highlighted at the basin center: linear, nonlinear, and ejection regimes. For moderate forcing, spatial profile breaks up-down symmetry as predicted third-order nonlinear theory, whereas for stronger maximum height reached gravity-wave crest, center, is found to increase linearly with its wavelength, consequence saturation steepness.
