Seismic metamaterial

A seismic metamaterial is a metamaterial that is designed to counteract the adverse effects of seismic waves on artificial structures. Current designs of seismic metamaterials use configurations of boreholes, trees, or proposed underground resonators to act as a large-scale material. Experiments have observed both reflections and bandgap attenuation from artificially induced seismic waves. These are the first experiments to verify that seismic metamaterials can be measured for frequencies below 100 Hz, where damage from Rayleigh waves is the most harmful to artificial structures.
