Direct impedance eduction of acoustic liners in multimodal ducts with shear flows

Jinyue Yang, Thomas Humbert, Joachim Golliard, Gwénaël Gabard

Impedance eduction of acoustic liners with flow is usually performed under the assumption of a uniform mean flow and in the presence of an incident plane wave. However, recent studies have demonstrated that shear flow significantly influences the propagation of sound waves and their interaction…

Rapid characterisation of millimetre-tall vertically aligned carbon nanotube arrays: growth optimisation by tuning the catalyst film thickness

Xinghai Zhao, Johannes Eduard Stubbe, Jin Chuen Kenneth Ho, Putu Andhita Dananjaya, Wen Siang Lew, Philippe Coquet, Beng Kang Tay

This study aims to establish a quick and sustainable approach for optimising the growth of millimetre-tall vertically aligned carbon nanotube (VACNT) arrays through simple catalyst tuning. To achieve this swiftly, a rapid and handy characterisation protocol is essential. Herein, we propose and…

Dynamics of the harmonic acoustic pneumatic source for active control of time-varying tonal noise

Alexandre Schiavini, Philippe Micheau, Pierre Grandjean, Gwénaël Gabard, Thomas Humbert

The Harmonic Acoustic Pneumatic Source (HAPS), a mechanical airflow modulator, is a promising alternative to loudspeakers as secondary sources for the active control of harmonic noise, thanks to its ability to generate high sound pressure levels and to precisely control signal frequency, phase, and…

Microcavités pour composants RF-SOI-CMOS ultra-rapides pour application 5G et delà, Microcavities for ultra-fast RF-SOI-CMOS components for 5G applications and beyond

Daniel Gheysens

Le développement des standards de communication mobile impose des exigences toujours plus strictes aux commutateurs radiofréquence (RF), notamment en termes de bande passante, pertes, linéarité et bruit. La technologie RF SOI-CMOS partiellement déplétée s’est imposée comme la solution dominante…, The development of mobile communication standards imposes increasingly stringent requirements on radio frequency (RF) switches, particularly in terms of bandwidth, losses, linearity, and noise. Partially depleted SOI-CMOS RF technology has emerged as the dominant solution thanks to an optimal…

Quantum Coherent Transport of 1D ballistic states in second order topological insulator Bi$_4$Br$_4$

Jules Lefeuvre, Masaru Kobayashi, Gilles Patriarche, Nathaniel Findling, David Troadec, Meydi Ferrier, Sophie Guéron, Hélène Bouchiat, Takao Sasagawa, Richard Deblock

We investigate quantum transport in micrometer-sized single crystals of Bi$_4$Br$_4$, a material predicted to be a second-order topological insulator. 1D topological states with long phase coherence times are revealed via the modulation of quantum interferences with magnetic field and gate voltage…
