An acoustical levitation trap can be created by maximizing the Laplacian of the Gor'kov potential and minimizing the pressure at a given location. Marzo et al. have successfully used Broyden-Fletcher-Goldfarb-Shanno minimization to find the phases to be imposed on the elements of an ultrasonic transducer array to create the required pressure field. We extend this method to create a field with one acoustical trap and a quiet zone at a different location. This can be used to, for example, createdoi:10.1109/sam.2018.8448949 dblp:conf/ieeesam/AnderssonA18 fatcat:moi2bjtbozbdba5cgbc5ejvjsq
