# Seismic Waveguide of Metamaterials

@article{Kim2012SeismicWO, title={Seismic Waveguide of Metamaterials}, author={Sang-Hoon Kim and Mukunda P. Das}, journal={Modern Physics Letters B}, year={2012}, volume={26}, pages={1250105} }

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…
