In the past decades, many mechanical metamaterials with uncommon static properties have
been reported. On the other hand, mechanical metamaterials possessing extraordinary …

Guided waves, elastic waves propagating through bounded structures, play a pivotal role in
various applications, including ultrasonic non-destructive testing and structural health …

Metamaterials with low-frequency and broadband bandgaps have great potential for
manipulating elastic/acoustic waves. Inspired by the frame structures that are widely used in …

We study numerically and experimentally acoustoelastic wave propagation in a two-
dimensional phononic metaplate consisting of a periodic array of cups sitting on a thin epoxy …

We investigate two-dimensional phononic metaplates consisting of a periodic array of cups
on a thin epoxy plate that is perforated with periodic cross holes. The cups are individually …

Defect states of phononic crystals (PCs) have attracted fast-growing attention due to the
elastic wave localization phenomenon. However, how to effectively regulate multiple defect …

Phononic crystals (PnCs) exhibit acoustic properties that are not usually found in natural
materials, which leads to the possibility of new devices for the complex manipulation of …

Artificial structures known as phononic crystals and acoustic metamaterials can be designed
by spatially arranging one or more materials to obtain desired wave manipulation …

Topology optimization has become a useful tool for designing Phononic Crystals (PnCs) to
achieve desired elastic wave propagation properties. However, topological design of three …

A semi-analytical method is developed to calculate the wave propagation properties of thin
orthotropic composite plate structures periodically attached to acoustic black hole (ABH) …
