[HTML][HTML] Roton-like dispersion via polarisation change for elastic wave energy control in graded delay-lines

L Iorio, JM De Ponti, F Maspero, R Ardito - Journal of Sound and Vibration, 2024 - Elsevier
While roton dispersion relations had been restricted to correlated quantum systems at low
temperature, recent works show the possibility of obtaining this unusual dispersion in …

Rayleigh waves isolation based on metamaterials surface

L Zhou, S Wan - Mechanics of Advanced Materials and Structures, 2023 - Taylor & Francis
Elastic metamaterials (EMMs) can attenuate surface Rayleigh waves effectively, However, it
still hard to put EMMs in practical engineering applications. To overcome this limitation …

Bandgap widening and resonator mass reduction through wave locking

L Iorio, JM De Ponti, A Corigliano, R Ardito - Mechanics Research …, 2023 - Elsevier
Elastic metamaterials made of locally resonant arrays have been developed as effective
ways to create band gaps for elastic or acoustic travelling waves. They work by …
