  • Air coupled acoustic aperiodic flat lens
    Patent number: 8616329
    Abstract: A broadband acoustic lens and method of designing same is provided for focusing an incident acoustic wave. The broadband lens includes a plurality of concentric rings, where each concentric ring of the plurality of concentric rings has a ring width, and a plurality of gaps, where each gap of the plurality of gaps has a spacing. The concentric rings are separated by a spacing corresponding to a gap of the plurality of gaps. The widths of the plurality of concentric rings and the spacings of the plurality of gaps are arranged such that the incident acoustic wave is focused to a spot within a sub-wavelength of the incident acoustic wave in air. The arrangement of the widths of the plurality of concentric rings and spacings of the plurality of gaps is aperiodic.
