Noise barriers are the most widespread solution to mitigate noise produced by the
continuous growth of vehicular traffic, thus reducing the large number of people exposed to it …

Owing to a steep rise in urban population, there has been a continuous growth in
construction of buildings, public or private transport like cars, motorbikes, trains, and planes …

The proposed structure comprises an array of elastomeric helices that can be easily
stretched in the axial direction (see Figure 1). In the undeformed configuration the helices …

We combine numerical simulations and experiments to design a new class of reconfigurable
waveguides based on three-dimensional origami-inspired metamaterials. Our strategy …

Stubbed plates, ie, thin elastic sheets endowed with pillar-like resonators, display
subwavelength, locally resonant bandgaps that are primarily controlled by the intrinsic …

This work presents sound insulation and sound reflection measurements conducted over
sonic crystal noise barriers according to the European standards EN 1793-2, EN 1793-5 and …

Composite materials with engineered band gaps are promising solutions for wave control
and vibration mitigation at various frequency scales. Despite recent advances in the design …

A novel design of origami phononic structures with tunable waveguiding features are
studied in this research. The structure is formed by attaching cylindrical inclusions on top of …

We introduce a framework of utilizing origami folding to redistribute the inclusions of a
phononic structure to achieve significant phononic band-gap adaptation. Cylindrical …

Locally resonant phononic crystals (LRPC) are able to give low-frequency band gap to
attenuate the vibration in a specific frequency range; however, the local resonance band …
