    Abstract: When designing acoustic metamaterials for complex environments, it is very challenging to derive the acoustic field distribution analytically and obtain the desired devices with the conventional method. Here, we propose to optimize some acoustic devices with inversely design method, which can actively find the optimized structure parameters with prescribed property. This inverse design method avoids the complex analytical calculation and can obtain some performances that are not attainable with the conventional method. This inverse design method takes a significant step towards realizing practical devices and would open up new possibilities for manipulating sound wavefront with optimized performances.

    Abstract: A theoretical solution of the acoustic radiation force (ARF) on spherical particles by an arbitrary beam in viscous fluids in a tube is proposed. Based on the parametric design with the purpose of promoting calculi in the urinary system, theoretical solutions and finite element simulations are carried out, which mutually confirm the accuracy and feasibility of the scheme. The variation law of the ARF with adjustable parameters, such as incident angle, frequency spectrum, particle radius, tube radius, and viscosity, is studied, and the mechanism of the variation law is explained. This solution lays a foundation for the application of non-contact and non-invasive in-tube manipulation based on ARF in medicine and life sciences.

    Abstract: Many bat species exhibit conspicuous ear movements as part of their biosonar behaviors. The resulting transformations of the pinnae can contain rigid rotations as well as nonrigid deformations. Characteristic ear deformations are frequently observed in horseshoe bats (Rhinolophidae). In these animals, the pinna changes regularly between an upright and a bent configuration. In the bent configuration, the tip of the pinna tilts forward, down, and sideways, changing the curvature of large portions of the ear surface. Entire deformation cycles can be completed in as little as 200 ms. The time-variant geometry of the pinna deformations in the greater horseshoe bat (Rhinolophus ferrumequinum) was captured with a stereo pair of high-speed video cameras. Landmark points were marked on the pinna with dyes that were equally visible in the video frames as in x-ray micro-CT. The CT model was matched to the locations of the landmarks in the deforming ears inferred from stereo reprojection. Numerical predictions were obtained for the acoustic behavior of ear shapes at different phases during the deformation cycle. It was found that the pinna deformations seen in the animals can produce large changes in the directivity patterns. [Work supported by NSFC (Project No. 10774092) and CSC.]

    A kind of polar coordinate system adaptable metasurface and its broadband wavefront manipulation

    Abstract: We report a type of polar coordinate system adaptable metasurface by which a three-dimensional Bessel beam in broadband of 2–6 kHz is realized. For the common design of metasurface, many kinds elements are for a square lattice in the Cartesian coordinate system while sometimes a cylindrical symmetric source can be more suitable for practical working conditions, the 3D Bessel beam for example. Here, we present a unit cell for metasurface by embedding helical blades into an element of required shape. Thus, the lattice structure can be adjusted easily to the distinct coordinate systems. Hence, the arrangement of the elements can be more flexible, which means a larger freedom of design for the requirement of bi-anisotropic metasurfaces can be obtained. With the advantage of helical blades, an ideal control over energy transmission efficiency can be achieved too. Based on this, we investigated the characteristics and performance of the elements and realized a better performed Bessel beam in three dimensional. This design thinking can also be utilized to other kinds of wavefront modulation in broadband for both transmission and reflection control.

    Abstract: We present here the involvement of inverse design method with the acoustic wave modulation, to simplify how we get the required material parameters and design novel acoustic devices that can perform certain prescribed operation. As an example, the acoustic cloaking will be discussed. The existing acoustic invisibility design based on coordinate transformation method needs negative index media which can be realized through complicate structures. With inverse design method, we have designed a circular cloak device with positive index materials, that successfully make a circular scatterer acoustically invisible. This inverse design method takes a significant step towards realizing practical cloaking devices and would open up new possibilities for manipulating acoustic wavefront with simplified parameter distribution and optimized properties.

    Abstract: Zero index metamaterials have shown the ability to achieve total transmission or reflection by embedding particular defects with various effective parameters. Here, we present that tunable sound transmission can be realized by configuring a subwavelength-sized dopant inside zero index acoustic metamaterials. Despite its small spatial signature, the dopant is able to strongly interact with the acoustic waves inside the whole zero index metamaterials. It is due to the essence of the zero effective index that can homogenize the pressure field within the metamaterials. Sound transmission can thus be fully switched on and off by adjusting the dopant's surface impedance. A simple rectangular cavity with varied lengths is proposed to provide the required impedance boundary. Our model of correlating the dopant design with sound transmission performance is validated theoretically and numerically. We further demonstrate the utilization of the proposed design to effectively modulate the sound focusing effect. Such a dopant-modulated sound transmission scheme, with its simplicity and capability, has potential applications in fields like noise control and ultrasonography.

    A digital model for the deformation of bat ears.

    Abstract: In bats, the directivity patterns of the biosonar system are shaped by the surface geometry of the pinnae. Since many bat species are capable of large ear deformations, these beampatterns can be time-variant. To investigate this time-variance using numerical methods, a digital model that is capable of representing the pinna geometry during the entire deformation cycle has been developed. Due to large deformations and occlusions, some of the surfaces relevant to sound diffraction may not be visible and hence the geometry of the entire pinna has to be computed from limited data. This has been achieved by combining a complete digital model of the pinna in one position with time-variant sparse sets of three dimensional landmark data. The landmark positions were estimated using stereo vision methods. A finite element model based on elasticity was constructed from CT scans of the pinna post mortem. This elastic model was deformed to provide a good fit to the positions of the landmarks and retain values of smoothness and surface energy comparable to life. This model was able to handle ratios of data to degrees of freedom around 1:5000 and still effect life-like deformations with an acceptable goodness of fit.
