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…

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,…

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…

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…

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…

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…

Impacts de jet : du ressaut hydraulique oscillant à la formation de spray sur surface chaude, Impact of jets : from oscillatory hydraulic spring to spray formation on hot surface

Aurélien Goerlinger

L'impact des jets sur diverses surfaces est au cœur de nombreuses problématiques, notamment en termes de refroidissement et de nettoyage de surface. Cette thèse se penche sur deux aspects différents de ce sujet pour des jets sub-millimétriques, peu étudiés dans la littérature.Dans un premier…, The impact of jets on various surfaces is at the heart of many problems, particularly in terms of cooling and surface cleaning. This thesis focuses on two different aspects of this subject for sub-millimeter jets, little studied in the literature.First, we explore the circular hydraulic jump…

Control of the preferentially orientated growth of Sr2TiSi2O8 crystals in a SrO – TiO2 – SiO2 – Al2O3 – K2O parent glass

Oussama Zwein, Marie-Sophie Renoirt, Maurice Gonon, Nicolas Preux, Sandra Abdelouhab, Rıdvan Yildiz, Marc Duquennoy

A polar glass-ceramic containing Sr-fresnoite Sr2TiSi2O8 (STS) as single crystalline phase was developed through the controlled crystallization of a parent glass composition containing SrO, TiO2, SiO2, K2O, and Al2O3. The objective of this work is to obtain a piezoelectric substrate exhibiting a…

LLR estimation using machine learning

Latifa Mostari, Alban Goupil, Abdelmalik Taleb-Ahmed

Many decoders of error-correcting codes use the Log-Likelihood Ratio (LLR) as an input, which involves the probability density function (pdf) of the noise. In impulsive noise, the pdf of the noise is not accessible in closed form and is only available through very complex numerical computation.…
