Band gap enhancement in periodic frames using hierarchical structures
Vinícius F. Dal Poggetto, Federico Bosia, Marco Miniaci +1
The quest for novel designs for lightweight phononic crystals and elastic metamaterials with wide lowfrequency band gaps has proven to be a significant challenge in recent years. I…
Effect of prestress on phononic band gaps induced by inertial amplification
M. Miniaci, M. Mazzotti, A. Amendola +1
We report about the effect of an applied external mechanical load on a periodic structure exhibiting band gaps induced by inertial amplification mechanism. If compared to the cases…
Valley based splitting of topologically protected helical waves in elastic plates
Marco Miniaci, Raj Kumar Pal, Raffaele Manna +1
Topological protection offers unprecedented opportunities for wave manipulation and energy transport in various fields of physics, including elasticity, acoustics, quantum mechanic…
A frequency-preserving and time-invariant metamaterial-based nonlinear acoustic diode
Antonio S. Gliozzi, Marco Miniaci, Anastasiia O. Krushynska +4
We present the realization of an acoustic diode or rectifier, exploiting symmetry-breaking nonlinear effects like harmonic generation and wave mixing and the filtering capabilities…
Observation of a Lamb band gap in a polymer waveguide with periodic cross-like cavities
M. Miniaci, M. Mazzotti, M. Radzieński +6
The quest for large and low frequency band gaps is one of the principal objectives pursued in a number of engineering applications, ranging from noise absorption to vibration contr…
Relaxed micromorphic modeling of the interface between a homogeneous solid and a band-gap metamaterial: new perspectives towards meta-structural design
Angela Madeo, Gabriele Barbagallo, Manuel Collet +3
In the present paper, the material parameters of the isotropic relaxed micromorphic model derived for a specific metamaterial in a previous contribution are used to model its trans…
