Satellite droplets that have a lifetime selectable between an infinite lifetime and a finite lifetime are formed with a continuous fluid-jet system having a drop generator, a stimulation device, and a nozzle plate with at least one nozzle opening. A force is applied to eject a fluid jet having a diameter D from the nozzle openings and an adjustable energy drive pulse is applied to the stimulation device in a manner to create a series of perturbations on the ejected fluid jet, such that the perturbations are separated by a distance λ. The drive pulse is defined by a pulse shape, a pulse amplitude, and a pulse duty cycle. A first satellite formation state is established by adjusting the energy of the drive pulse while operating the continuous fluid-jet system in a state wherein the λ/D values are greater than π and correspond to the measured normalized Rayleigh growth rate within or beyond the first minimum. The drive pulse is adjusted in a manner to bring about a second satellite formation state after at least 1 λ of the first satellite formation state.
