text: A popular method for generating micron-sized aerosols is to submerge ultrasonic
(ω ∼ MHz) piezoelectric oscillators in a water bath. The submerged oscillator
atomizes the fluid, creating droplets with radii proportional to the wavelength
of the standing wave at the fluid surface. Classical theory for the Faraday instability
predicts a parametric instability driving a capillary wave at the subharmonic
(ω / 2) frequency. For many applications it is desirable to reduce the size of
the droplets; however, using higher frequency oscillators becomes impractical
beyond a few MHz. Observations are presented that demonstrate that smaller droplets
may also be created by increasing the driving amplitude of the oscillator, and
that this effect becomes more pronounced for large driving frequencies. It is
shown that these observations are consistent with a transition from droplets associated
with subharmonic (ω/2) capillary waves to harmonic (ω) capillary waves induced
by larger driving frequencies and amplitudes, as predicted by a stability analysis
of the capillary waves.
