Influence of 3D printing parameters on acoustic properties of metamaterials

Abstract

Acoustic metamaterials such as transmission phase plates have the invaluable capability of manipulating the wavefront. Due to their subwavelength architected features, they have greatly benefitted from the power of 3D printing techniques. However, a detailed investigation of the acoustic capabilities of the 3D printed acoustic metamaterials is necessary, especially for applications such as high-power acoustic. In this paper, we showed that other than the material properties, printing parameter is also affecting the acoustic performance of the metamaterial, which can increase the efficiency of the acoustic energy transfer.
