Abstract:

An acoustically-focused optical lens is provided that uses acoustic transducers arranged in diametrically-opposed pairs around an exterior surface of a cylindrical tube to concentrate heavier-than-water metallic particles suspended in water within the interior of the tube to be along a central axis of the tube. The transducers are activated in accordance with higher order and odd order Bessel functions to create an asymmetric mode to create the central axis node. Distortions in the optical lens can be further reduced by arranging two or more of the tubes in series with their central axes aligned.
