A novel membrane-type acoustic metamaterial with a high sound transmission loss (STL) at
low frequencies (⩽ 500Hz) was designed and the mechanisms were investigated by using …

Phononic crystal sensor is a novel technology for sensing applications with high
performance. The present work proposes theoretically a design of gas (CO 2) sensor based …

This paper investigates the stopband of laminate acoustic metamaterials, which is
composed of carbon-fiber-reinforced polymer (CFRP) and a periodic array of mass-spring …

By replacing the rectangle cells with arbitrary triangle ones, an improved lumped-mass
method is introduced to study the propagation of flexural elastic waves in the infinite quasi …

The objective of this paper is to use transfer functions to comprehend the formation of band
gaps in locally resonant acoustic metamaterials. Identifying a recursive approach for any …

This paper introduces a new seismic isolation system called a periodic foundation (PF),
where inclusions are periodically arranged. The PF is different from traditional base isolation …

Elastic metamaterials are sub-wavelength structures with locally resonant components that
contribute to the rise of tunable stop bands, ie frequency ranges within which waves do not …

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 …

Inspired by some recent results in elastodynamics of layered composites, we address here
the problem of an antiplane elastic wave obliquely incident at the interface between a …

Elastic metamaterials have promising applications in wave control and vibration isolation,
due to their extraordinary characteristics, eg, negative Poisson ratio, band gaps, effective …
