ABSTRACT:
A method of ejecting a droplet of a fluid from a surface of the fluid includes the step of generating an acoustic wave to eject the droplet from the fluid surface. The acoustic wave is shaped into an optimal toneburst such that the droplet is ejected substantially in a direction of acoustic wave propagation substantially independent of an orientation of the fluid surface.
