“…Therefore, the design of a new structure with low-frequency noise and vibration attenuation properties has become the key to research. [41,42] In previous studies, the analysis of the propagation mechanism of elastic waves within the structure and the reason for the opening of the bandgap is relatively superficial, so the investigation of the real propagation direction of the waves within the new structure is particularly important.…”

Based on the idea of local resonance, a class of hybrid acoustic metamaterials with interposed resonant strips is proposed in this article, and the bandgap characteristics and transmission properties are calculated by combining Bloch's theorem and lattice theory. The new structure is verified to have low‐frequency damping and noise reduction capability through the analysis of the stress cloud diagram at specific frequencies in the bandgap range. A comprehensive analysis of vibration modes, phase constant surfaces, group velocity, phase velocity, and wave propagation direction diagram is used to explore the wave propagation and bandgap opening mechanism, providing technical support and theoretical basis for subsequent bandgap optimization and structural improvement. The results show that this structure can open multiple bandgaps in the low‐frequency range below 500 Hz, and the stepped design of the single‐cell structure and the introduction of resonant strips provide a new design idea for low‐frequency vibration and noise reduction.

“…According to the formation mechanism of the bandgaps, it can be physically classified into local resonance (LR) and Bragg scattering (BS) mechanisms. In general, all the above band gaps are the result of a combination of Mie scattering and structural periodicity, but the former is oriented to scatterer resonance while the latter is more dependent on periodicity [ 29 , 30 , 31 , 32 , 33 , 34 ]. Of course, the resonance of monopole, dipole, and even quadrupole features introduced by the multiple inclusions also adds diversity to the band structure.…”

Admittedly, the design requirements of compactness, low frequency, and broadband seem to constitute an impossible trinity, hindering the further development of elastic metamaterials (EMMs) in wave shielding engineering. To break through these constraints, we propose theoretical combinations of effective parameters for wave isolation based on the propagation properties of Lamb waves in the EMM layer. Accordingly, we design compact EMMs with a novel ultralow−frequency bandgap, and the role of auxeticity in the dissociation between the dipole mode and the toroidal dipole mode is clearly revealed. Finally, under the guidance of the improved gradient design, we integrate multiple bandgaps to assemble metamaterial barriers (MMBs) for broadband wave isolation. In particular, the original configuration is further optimized and its ultralow−frequency and broadband performance are proven by transmission tests. It is foreseeable that our work will provide a meaningful reference for the application of the new EMMs in disaster prevention and protection engineering.
