This paper studies the dynamic properties of a 3D chiral mechanical metamaterial, which
largely depend on tacticity describing the connection forms of the chiral unit. Based on the …

An integrated massive multiple-input multiple-output (mMIMO) antenna system loaded with
metamaterial (MTM) is proposed in this article for fifth-generation (5G) applications. Besides …

Microvibration is a severe issue that is present in many components on spacecraft, such as
cryocoolers, thrusters, solar arrays, and momentum/reaction wheel assemblies (M/RWAs) …

Realizing a low-frequency and broad bandgap is extremely challenging because the lattice
constant, equivalent stiffness, and equivalent density must be taken into account in practice …

There is increasing concern that the locally resonant phononic crystals (LRPCs) are used to
reduce low-frequency noise and vibration in ship and ocean engineering. In this work, the …

In this study, a lightweight cylindrical honeycomb sandwich structure with low-frequency
vibration attenuation ability is designed. An analytical model based on Love shell theory is …

Abstract Quasi-zero-stiffness (QZS) metamaterials play an important role in ultra-low
frequency vibration mitigation. In this study, a customized QZS metamaterial is proposed to …

In this study, a vibration isolator is designed using the Bragg scattering and local resonance
band gaps in a layered honeycomb meta-structure. Various studies have been conducted …

Acoustic and elastic waves carry a wealth of useful physical information in real world.
Sensing acoustic and elastic waves is very important for discovering knowledge in various …

This work presents the design, manufacture, and experimental testing of a three-
dimensional twisted phononic crystal made of a single-phase material. A broad …
