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…
Accordion-like metamaterials with tunable ultra-wide low-frequency band gaps
Anastasiia O. Krushynska, Ada Amendola, Federico Bosia +3
We study lightweight, elastic metamaterials consisting of tensegrity-inspired prisms, which present wide, low-frequency band gaps. For their realization, we alternate tensegrity el…
Labyrinthine acoustic metamaterials with space-coiling channels for low-frequency sound control
Anastasiia O. Krushynska, Federico Bosia, Nicola M. Pugno
We numerically analyze the performance of labyrinthine acoustic metamaterials with internal channels folded along a Wunderlich space-filling curve to control low-frequency sound in…
