Practical implementation of a scalable discrete Fourier transform using logical phi-bits: nonlinear acoustic qubit analogues
It is shown that multiple logical phi-bit large-scale unitary operations analogous to quantum circuits can be realized by design. Logical phi-bits...

Bandgap characteristics of the two-dimensional missing rib lattice structure
In this paper, the bandgap characteristics of a missing rib lattice structure composed of beam elements are investigated by using the Floquet-Bloch...

A brief review of metamaterials for opening low-frequency band gaps
Metamaterials are an emerging type of man-made material capable of obtaining some extraordinary properties that cannot be realized by naturally...

A new tunable elastic metamaterial structure for manipulating band gaps/wave propagation
A one-dimensional mechanical lattice system with local resonators is proposed as an elastic metamaterial model, which shows negative mass and...

Effects of time-delayed vibration absorber on bandwidth of beam for low broadband vibration suppression
The effects of time-delayed vibration absorber (TDVA) on the dynamic characteristics of a flexible beam are investigated. First, the vibration...

Multi-resonator coupled metamaterials for broadband vibration suppression
In this study, multi-resonator coupled metamaterials (MRCMs) with local resonators are proposed to obtain the multiple and wide band gaps. Kinetic...
