Poster: Self Inducing Subharmonic Waves


High frequency excitation at 100g acceleration amplitude drives new wave modes on a vertically vibrated sessile drop. We showcase a self inducing phenomenon that couples high-mode subharmonic waves. Unlike Faraday waves, the sessile drops experience a polar dependence of the parametric vibration. Rather than the harmonics of vertical vibration, it is the axisymmetric harmonic waves that induce azimuthal subharmonic waves near the contact line − for example, a two-mass parametric vibrated pendulum in harmonic-subharmonic coupling state. We therefore conclude that all subharmonic waves are not Faraday waves.
