Claim Text:
1. A method for continuously separating a second fluid or a particulate from a host fluid, comprising: flowing a mixture of the host fluid and the second fluid or particulate through an apparatus, the apparatus comprising: sending a voltage signal to drive the at least one ultrasonic transducer to create the multi-dimensional standing wave, such that the second fluid or particulate is continuously trapped in the standing wave, and then agglomerates, aggregates, clumps, or coalesces together, and subsequently rises or settles out of the host fluid due to buoyancy or gravity forces, and exits the flow chamber; wherein the multi-dimensional standing wave results in an acoustic radiation force having an axial force component and a lateral force component that are of the same order of magnitude; and wherein the ultrasonic transducer comprises:
