“…4(b)-4(e), there are lots of conceptions for the structurized resonator. By replacing the linear spring into elastic materials or structures, for instance, silicon rubber [49,51,[55][56][57] , membrane [50,58] , cantilever beam [52] , and polymer concrete [59] , the size of the metamaterial is drastically reduced. An additional advantage of replacing the spring by the elastic material is that the elastic material is capable of providing the restoring force in multiple directions.…”

Metamaterials are an emerging type of man-made material capable of obtaining some extraordinary properties that cannot be realized by naturally occurring materials. Due to tremendous application foregrounds in wave manipulations, metamaterials have gained more and more attraction. Especially, developing research interest of low-frequency vibration attenuation using metamaterials has emerged in the past decades. To better understand the fundamental principle of opening low-frequency (below 100 Hz) band gaps, a general view on the existing literature related to low-frequency band gaps is presented. In this review, some methods for fulfilling low-frequency band gaps are firstly categorized and detailed, and then several strategies for tuning the low-frequency band gaps are summarized. Finally, the potential applications of this type of metamaterial are briefly listed. This review is expected to provide some inspirations for realizing and tuning the low-frequency band gaps by means of summarizing the related literature.

“…Deng et al (2022) used a set of periodic local resonators attached to an acoustic black hole plate, for broadband vibration reduction in a wide frequency range. The design method of the local resonator, for elastic metamaterial plates vibration suppression is examined by Lu et al (2020). Ma et al (2022) showed that the planar unit cell has stronger biostability than the cylindrical for elastic energy dissipation and shock isolation.…”

In the present work, sound transmission loss (STL) of two plates functionally graded sandwich structures with a porous core is studied. The plates are modeled by first-order shear deformation theory. To obtain an acoustic metamaterial plate with the greatest STL, a functionally graded porous (FGP) plate with a tuned mass damper absorber is used. The obtained results show that using a FGP plate or using only an absorber is sufficient for increasing sound transmission loss, but the simultaneous use of them is effective in higher frequencies.

“…Meng et al established a theoretical model for joining multiple locally resonant bandgaps of two-phase composites by damping. Based on the model, two-phase locally resonant materials were optimized to obtain a super-wide bandgap [ 40 ]. Lu et al designed a new type of metamaterial plate and analyzed its vibration characteristics by using the finite element method.…”

This paper reports a plate-type metamaterial designed by arranging unit cells with variable notched cross-sections in a periodical array for broadband high-frequency vibration attenuation in the range of 20 kHz~100 kHz. The dispersion relation and displacement field of the unit cell were calculated by simulation analysis, and the causes of the bandgap were analyzed. By studying the influence of critical structural parameters on the energy band structure, the corresponding structural parameters of a relatively wide bandgap were obtained. Finally, the plate-type metamaterial was designed by arranging unit cells with variable notched cross-sections in the periodical array, and the simulation results show that the vibration attenuation amplitude of the metamaterial can reach 99% in the frequency range of 20 kHz~100 kHz. After fabricating the designed plate-type metamaterial by 3D printing techniques, the characterization of plate-type metamaterial was investigated and the experiment results indicated that an 80% amplitude attenuation can be obtained for the suppression of vibration with the frequency of 20 kHz~100 kHz. The experimental results demonstrate that the periodic arrangement of multi-size cell structures can effectively widen the bandgap and have a vibration attenuation effect in the bandgap range, and the proposed plate-type metamaterial is promising for the vibration attenuation of highly precise equipment.
