The design of an acoustic lens that reduces the diffraction spreading from an ultrasonic transducer to produce a narrow focused beam is proposed. Lens Design A lens design must consider beamwidth sidelobe amplitudes field of view and lens efficiency. There are many optical lens design computer The Proceedings of Oceans 99. Based on this lumped network an acoustic negative index lens is implemented by a two-dimensional 2D array of subwavelength Helmholtz resonators. This allows for thinner lenses that can achieve the same focal distance with less impedance mismatch and fewer materials1012 Here a hyperbolic secant distribution is imposed because it produces lenses free of aberrations.
