single-phase metamaterial (spm) as a dissipater for attenuation of vibration in two-dimensional elastodynamics problems

The propagation of waves at different frequencies can be controlled using metamaterials. in general, a metamaterial cell consists of an inner core with a large mass and a high hardness and an external sheath with low mass and stiffness. these cells are arranged to form an interconnected chain and cause a reduction in vibration by creating a frequency vacuum.in 2014, the laboratorial investigations of yan and colleagues in the field of implementing metamaterials in structure’s foundation indicate appropriate performance of this system. in 2017, maleki and khodakarami (2017) investigated the use of metamaterial in soil to improve seismic performance and reduce in topography vibration.
