Abstract

In this paper, a reconfigurable frequency-selective acoustic coding metasurface is proposed for realizing multifunctional wavefront manipulation including sound focusing, beam splitting, and Airy beam. The acoustic coding unit is composed of three rotatable slitted round tubes of different sizes with extended necks. Independent manipulation of the reflected phase at different frequencies and the conversion between logical unit 0 and logical unit 1 can be achieved by changing the rotation angle of each slitted round tube. The feasibility of the proposed reconfigurable acoustic coding metasurface with multifunctionality is verified by theoretical analysis, numerical simulations, and experimental results. The proposed metasurface has the advantages of reconfigurability, multifunctionality, and multifrequency. Our work provides promising potential applications in multi-beam shaping, energy harvesting, and functional devices with special dispersion properties.

期刊介绍： Since its launch in 1968, Applied Acoustics has been publishing high quality research papers providing state-of-the-art coverage of research findings for engineers and scientists involved in applications of acoustics in the widest sense. Applied Acoustics looks not only at recent developments in the understanding of acoustics but also at ways of exploiting that understanding. The Journal aims to encourage the exchange of practical experience through publication and in so doing creates a fund of technological information that can be used for solving related problems. The presentation of information in graphical or tabular form is especially encouraged. If a report of a mathematical development is a necessary part of a paper it is important to ensure that it is there only as an integral part of a practical solution to a problem and is supported by data. Applied Acoustics encourages the exchange of practical experience in the following ways: • Complete Papers • Short Technical Notes • Review Articles; and thereby provides a wealth of technological information that can be used to solve related problems. Manuscripts that address all fields of applications of acoustics ranging from medicine and NDT to the environment and buildings are welcome.
