COMM

Topologically protected bound modes in non-neighboring hexagonal lattices

Vinicius Dal Poggetto, Raj Pal, Nicola Pugno, Marco Miniaci

In the last decade, the study of wave localization and guiding has gained a renewed interest thanks to the introduction of the concept of topological protection. Originally developed in the field of quantum mechanics, topological protection has successively inspired the search for its analogue in…

COMM

Anthropogenic noise and impact on marine species : Acoustic metamaterials as a reduction solution

Juliette Kessler, Charles Croënne, Monique Pouille, Céline Drouet, Anne-Christine Hladky-Hennion

Anthropogenic underwater noise generated by offshore maritime activities poses a significant threat to nearby ecosystems due to elevated sound levels. Efforts have to be undertaken on noise reduction solutions, depending both on the offshore activities and on the marine species. In this context,…

COMM

Design and analysis of a periodic metamaterial barrier for mitigating urban-induced vibrations

Slimane Ouakka, Bart van Damme, Yan Pennec, Georges Kouroussis

Urban areas are increasingly subjected to vibrations from various sources within the urban environment. Therefore, there is an urgent necessity to find measures that can minimize their negative effects. This pa-per investigates the concept of metamaterial and analyzes the impact of its inclusion on…

COMM

Characterisation of metamaterials for underwater acoustics using the 5-point method

Clément Larcade, Charles Croënne, Monique Pouille, Laetitia Roux, Anne-Christine Hladky

The characterization of metamaterials by measurement is essential to reveal the true efficiency of a material's reflection and transmission in water. The current 3-point method developed by L. Roux et al, J. Acoust. Soc. Am. 147, 2 (2020) 1104-1112 provides important advantages, such as…

COMM

Perception of audified acoustic emissions from compression of microscopic samples

Florian Duval, Clement Xu, Catherine Lavandier, Arthur Paté, Dávid Ugi, Péter Dusán Ispánovity, Szilvia Kalacska

Recording of acoustic emissions (elastic waves emitted by dislocation motion) during compression of microscopic samples is a novel emerging tool for the investigation of mechanical properties of materials. Yet the resulting signals can be so noisy and complex that they don't easily allow for…

COMM

Hierarchical porous metamaterial for sound absorption

Svetlana Kuznetsova, Florian Allein, Samuel Deleplanque, Bertrand Dubus, Marco Miniaci

Absorption of sound is of great importance in several engineering applications, from room acoustics to engine noise reduction. Porous media are practical and commonly used to address this issue. However, their performance is limited at large wavelengths, where more material is required. Inspired by…

COMM

Diatom frustule-inspired elastic metamaterials

Chiara Gazzola, Vinicius Fonseca Dal Poggetto, Xin Zhou, Marco Miniaci

Although a universally accepted definition of elastic metamaterials does not exist yet, the latter are often associated to man-made or artificially engineered media possessing properties typically not available in Nature. Pioneering studies have recently demonstrated that complex structural…
