We developed a new method of an earthquake-resistant design to support conventional aseismic system using acoustic metamaterials. The device is an attenuator of a seismic wave that reduces the amplitude of the wave exponentially. Constructing a cylindrical shell-type waveguide composed of many Helmholtz resonators that creates a stop-band for the seismic frequency range, we convert the seismic wave into an attenuated one without touching the building that we want to protect. It is a mechanical…

There are two methods for earthquake engineering as an application of acoustic metamaterials. One is the traditional cloaking method that makes the seismic wave deflect the building to be protected.
Seismic isolation of buildings using composite foundations based on metamaterials
TLDR
A different approach to seismic isolation by using certain principles of seismic metamaterials is introduced, including the local resonance and a dual-stiffness structure that preserves large (small) rigidity for compression (shear) effects.
Seismic metamaterials based on isochronous mechanical oscillators
This Letter introduces a seismic metamaterial (SM) composed by a chain of mass-in-mass system able to filter the S-waves of an earthquake. We included the effect of the SM into the mono dimensional

Broadband cylindrical acoustic cloak for linear surface waves in a fluid.
TLDR
This work describes the first practical realization of a cylindrical cloak for linear surface liquid waves and demonstrates theoretically its unique mechanism using homogenization theory: the cloak behaves as an effective anisotropic fluid characterized by a diagonal stress tensor in acylindrical basis.
