Study of Faraday waves in tanks in presence of polystyrene bead layers

When a tank is subjected to vertical forced excitation, Faraday waves appear at the surface of liquid contains. In this paper, we consider effect layers polystyrene beads placed on isopropanol undergoing low frequency sinusoidal excitation. Beads remove most low-frequency resonances and reduce amplitude for remaining ones. The formation with observed come from small gaps in bead layers. A sufficient number needed maintain one compact block prevent waves.
