摘要：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.
