“…Acoustic metamaterials are a type of architect material that is designed to control and manipulate waves passing through it. The periodic structures as a kind of metamaterials have the ability to damp some specific frequency ranges of elastic waves, called bandgap or stopband D'Alessandro, Zega, Ardito, & Corigliano, 2018;Li, Wang, & Yan, 2021;Meaud & Che, 2017). In other words, while elastic wave propagation occurs in all directions in the propagating frequency ranges, bandgap areas provide a frequency range where elastic wave propagation is stopped, and this ability can be used in a variety of applications, including controlling and managing wave propagation and acoustic mirrors.…”

“…The researchers have designed adaptive structures with variable and uncommon behavior in different applications. Therefore, by employing different methods, researchers have tried to design and fabricate adaptive and tunable structures Bertoldi, Boyce, Deschanel, Prange, & Mullin, 2008;D'Alessandro et al, 2018;Li et al, 2021;Li, Wang, Chen, Wang, & Bao, 2019;Meaud & Che, 2017;Shim, Wang, & Bertoldi, 2015;Singh & Pandey, 2018).…”

“…However, it is readily extendable to more complex configurations in higher dimensions. For example, a quasi-1D configuration comprising multiple interconnected layers of masses and springs could form the base chain [36]. Realization using standard mechanical components such as rods and beams is also possible [22,28].…”

“…6,7 As a kind of artificial inhomogeneous material, acoustic metamaterials are synthetic materials formed by a periodic variation in the mechanical properties of materials (i.e., elasticity modulus and mass density), and it can suppress and manipulate acoustic waves transmission. [8][9][10][11] Acoustic metamaterials have unique mechanical properties, such as negative equivalent mass density, negative equivalent bulk modulus, and negative shear modulus, which are achieved through topology design of micro-structure and materials distribution design. [12][13][14] Acoustic scattering is caused by acoustic reflection of the interface, obstacles, or targets in the acoustic transmission process; reducing acoustic scattering is of great significance to improve the acoustic stealth ability.…”
