Seismic surface waves, composed of many complex waves and difficult to attenuate, can be controlled and obstructed by seismic metamaterials applied in civil engineering to protect sensitive buildings, such as nuclear power plants and ancient buildings. In this paper, a seismic metamaterial based on...
