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 …

Inspired by sonic engineering, locally resonant metamaterials have attracted much attention
from researchers in civil engineering for their unique characteristics of stress wave …

This study proposes a viscoelastic metamaterial containing negative-stiffness elements,
which exhibits both a damping enhancement effect and a tunable ultra-low frequency band …

In this paper, a metamaterial with time-delayed feedback control for broadband vibration
suppression is investigated. Genetic algorithm is used to optimize the time-delayed …

As an innovative planar artificial structure, elastic metasurface exhibits great potential in the
application fields of vibration and noise control. By virtue of the superior performance of …

In order to realize the vibration reduction and sound insulation within the recognizable
frequency of human ear within 20000 Hz, this paper proposes a new type of multi-functional …

This paper presents two novel cruciate ligament structures with outstanding contributions in
lightweight design of metamaterials, band gap tuning, and ultra-wide and ultra-low …

In this paper, we establish a theoretical framework for joining multiple locally resonant
bandgaps of composites that consist of a continuous matrix and discrete particles towards a …

Acoustic Metamaterial have been widely concerned because of their strong sound insulation
characteristics for specific low-frequency bands. However, further optimization is still needed …
