Abstract
dc.description.abstract
We report on the generation of an intermittentwave field driven by a horizontallymovingwave maker interacting
with Faraday waves. The spectrum of the local gravitocapillary surface wave fluctuations displays a power law
in frequency for a wide range of forcing parameters. We compute the probability density function of the local
surface height increments, which show that they change strongly across time scales. The structure functions of
these increments are shown to display power laws as a function of the time lag, with exponents that are nonlinear
functions of the order of the structure function. We argue that the origin of this scale-invariant intermittent
spectrum is the Faraday wave pattern breakup due to its advection by the propagating gravity waves. Finally,
some interpretations are proposed to explain the appearance of this intermittent spectrum.
