Abstract
Acoustic patterning and focusing is an interdisciplinary topic covering a wide range of applications. A particular challenge arises from the nonlinear distortion of the pressure waveforms that occurs at high acoustic intensities. Such a phenomenon, if not treated, limits the control of the sound field in the nonlinear range, reducing the localization and efficiency. In this work, we investigate acoustic holographic lenses for constructing precise nonlinear acoustic fields. Such passive structures provide higher fidelity at a fraction of the cost of the expensive and complex phased array transducers.
