High load-bearing metastructure for controlling surface Rayleigh waves

Abstract

Artificial metamaterials for controlling surface Rayleigh waves have been extensively studied in recent years. However, practical engineering applications of metamaterials are still limited when they lack high load-bearing capacity. For this reason, a new metamaterial called a high-load-bearing metastructure is presented, which is designed by generalized Snell’s law. The wide-bandgap performance for surface Rayleigh waves and the high load-bearing capacity of the proposed metastructure are realized by using traditional engineering materials, which provide a more flexible reference in practical engineering applications. This work can open new avenues for controlling the propagation of surface Rayleigh waves.
