In solid state physics, a bandgap (BG) refers to a range of energies where no electronic
states can exist. This concept was extended to classical waves, spawning the entire fields of …

Achieving broadband low-frequency surface wave bandgaps is technically challenging,
which calls for a systematic design paradigm instead of intuitive approaches. In this study …

The use of artificial periodic structures such as periodic wave barriers and seismic
metamaterials has attracted attention as an effective approach to reduce the impact of …

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 …

The ground‐borne vibration generated by moving trains has become an important
environmental problem. Research on mitigation measures has been uninterrupted for …

The frequency attenuation zones (AZs) of periodic pile barriers have attracted extensive
attention in recent years due to their superior performance in ambient vibration reduction …

A deep learning model consisting of a variational autoencoder (VAE) and a tandem neural
network (TNN) is presented to realize the inverse design of a locally resonant metabarrier for …

Periodic pile barriers, which are used to isolate ambient vibrations from traffic, are
traditionally limited by their narrow attenuation zones (AZs) and simple unit structures …

Semi-infinite elastic metamaterials and metasurfaces on homogeneous elastic half-spaces
have attracted significant attention in the past two decades as efficient artificial structures to …

Ground vibrations induced by underground transportation, human activities, and
earthquakes can damage civil infrastructures. The damage can be more pronounced in …
