In recent years, elastic metamaterials inspired from electromagnetic metamaterials have
been used to protect buildings during earthquakes, and their effectiveness in seismic wave …

Resonant metamaterials have been proposed to reflect or redirect elastic waves at different
length scales, ranging from thermal vibrations to seismic excitation. However, for seismic …

In elastic wave systems, combining the powerful concepts of resonance and spatial grading
within structured surface arrays enable resonant metasurfaces to exhibit broadband wave …

The purpose of this study is to investigate surface-wave isolation by periodic piles from the
perspective of attenuation zones. There are three major components. The first is the …

Artificial soils engineered with periodic or resonant structures, also referred as “seismic
metamaterials” have been investigated for earthquake mitigation applications. In particular …

In recent years, a new type of seismic isolation system which exploits the filtering effect of
bandgaps, named Periodic Foundation, has been proposed to isolate the upper structure …

This paper studies periodically arranged seismic barriers consisting of finite and infinite
lattices to mitigate seismic surface waves in layered soils. Using Bloch-Flouquet theory …

This paper proposes a novel multidimensional composite periodic foundation for seismic
isolation. The composite periodic foundation achieves multidimensional attenuation by …

Surface wave manipulation in periodic trench barriers based on real band structures has its
inherent limitations. This work revisits this problem from the perspective of complex band …

In this study, the propagation of surface waves in both one-and two-dimensional periodic
structures is investigated. By combining finite element method, an energy distribution …
