Abstract
A system is provided that includes one or more acoustic microfilters through which is flowed a mixture of a fluid and a particulate to selectively filter particles from the fluid. Also included are one or more phononic crystal units coupled to the acoustic microfilter(s) to further selectively filter particles from the fluid. Related apparatus, systems, techniques and articles are also described.
