Abstract: We report zero-th and high-order acoustic Bessel beams with broad depth-of-field generated using acoustic holograms. While the transverse field distribution of Bessel beams generated using traditional passive methods is correctly described by a Bessel function,… read more here.

DOI: 10.1109/tuffc.2023.3264580
Abstract: Acoustical hologram generation can be achieved via controlled beam shaping by engineering the transmitted phases to create a desired pattern. Optically inspired phase retrieval algorithms and standard beam shaping methods assume continuous wave (CW) insonation,… read more here.
