WebJul 7, 2024 · Zeng et al. developed a seismic metamaterial capable of attenuating seismic surface waves between about 0.5 and 22.0 Hz, covering the resonance frequency range of most human-made structures. When partially buried in the ground encircling a building or a set of buildings, the material isolates seismic surface waves that can cause resonance. WebThe theory and ultimate development for the seismic metamaterial is based on coordinate transformations achieved when concealing a small cylindrical object with electromagnetic waves. This was followed by an analysis of acoustic cloaking, and whether or not coordinate transformations could be applied to artificially fabricated acoustic materials.

Using more than one material, Chen et … Webposed seismic metamaterials are constructed by periodically varying concrete piles in the host multi-layered soil. We first validate the design concept and the numerical models by performing a lab-scale experiment on the low-amplitude surface wave propagation in a finite-size seismic metamaterial.
