Spatiotemporal resonances in a microfluidic system.
We report on the experimental observation of a spatiotemporal resonance phenomenon, in which a temporal excitation locks with a spatial pattern in an open flow system. The observation is made in a microfluidic system. We obtain the expected regimes--mixing and resonant patterns--in qualitative agreement with the theory. As an application, we realized a dual system particle extraction-micromixer.
