Abstract
An apparatus includes an acoustic source for directing an acoustic wave towards a workspace, a variable acoustic diffractive device positioned in a path of the acoustic wave between the acoustic source and the workspace, the variable acoustic diffractive device including an array of elements each having independently variable acoustic properties, and an electronic controller in communication with the acoustic source and the variable acoustic diffractive device, the electronic controller programmed to supply signals to cause the acoustic source to produce the acoustic wave and the variable acoustic diffractive device to diffract the acoustic wave from the acoustic source to provide non-uniform acoustic forces in a medium located in the workspace.
