The frequency dispersion characteristics of pile barriers are receiving more attention due to
their effectiveness and a better understanding of their behavior at attenuating middle and …

It is common for dispersion curves of damped periodic materials to be based on real
frequencies as a function of complex wavenumbers or, conversely, real wavenumbers as a …

This paper presents the modeling technique, the design method, the local resonator with
new modes of action, and influence factors for elastic metamaterial plates with broadband …

This paper deals with flexural wave band gaps in metamaterial beams with membrane-type
resonators. The proposed membrane-type resonator consists of a tensioned elastic …

To meet the demand of modern acoustic absorbing material for which acoustic absorbing
frequency region can be readily tailored, we introduced woodpile structure into locally …

In this paper, a physical platform is proposed to change the properties of phononic crystals
in space and time in order to achieve nonreciprocal wave transmission. The utilization of …

This paper presents the modeling technique, design method, a new working mechanism
and influence factors for elastic metamaterials (EMs) with parallel multi-resonators for …

Three-dimensional (3D) locally resonant sonic materials (LRSMs) are studied theoretically
for purpose of optimising their sub-wavelength performance by coupling resonance and …

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 …

To determine the flexural vibration band gaps in periodic beams, the theoretical equations
are derived by employing the Bloch–Floquet theorem and then solved by the use of the …
