Unlike conventional metamaterials with a periodic array of identical resonators, rainbow
metamaterials consist of an array of discrete resonators with a spatially varying parameter …

This paper investigates the influences of nonperiodic rainbow resonators on the vibration
attenuation of two-dimensional metamaterial plates. Rainbow metamaterial plates …

In this study, we propose a 'rainbow'metamaterial to achieve broadband multi-frequency
vibration attenuation. The rainbow metamaterial is constituted of a Π-shaped beam …

Metamaterials have received extensive attention due to their special properties in the fields
of wave attenuation and acoustic engineering. Many researchers have designed …

Phononic crystals (PnCs) and metamaterials are widely investigated for vibration
suppression owing to the bandgaps, within which, wave propagation is prohibited or the …

A novel metamaterial multi-span beam with periodic simple supports and local resonators is
designed and investigated. The frequency responses of the proposed metamaterial multi …

How to endow diverse functions for lightweight structures without increasing mass has
always been a major challenge (eg, to have simultaneous high static stiffness and extreme …

We propose a metamaterial beam having multiple corrugated parts for broad band gaps,
study its band gap properties, and investigate the potential of the proposed beam in …

Vibration suppression at subwavelength scales is of great interest in acoustic and/or elastic
metamaterial engineering which has a wide range of potential applications requiring …

Acoustic black hole (ABH) structures have been widely utilized for vibration suppression
owing to its tailored indentations according to a power-law profile. Compared with single …
