Seismic metamaterials: Generating low-frequency bandgaps induced by inertial amplification
Yi-Xin Zeng,Liyun Cao,Shengpeng Wan,Tong-qing Guo,Yan-Feng Wang,Qiu-Jiao Du,Badreddine Assouar,Yue-Sheng Wang +7 more
TL;DR: In this article , an alternative type of seismic metamaterial with a low-frequency bandgap induced by inertial amplification was proposed for isolating seismic surface waves. But the authors did not consider the effects of the metammaterial plate in the bandgap on the propagation of the flexural waves.
