Spectral flow of a localized elastic mode

M. Miniaci, F. Allein, R. K Pal

The introduction of structural defects in otherwise periodic media is well known to grant exceptional space control and localization of waves in various physical fields, including elasticity. We theoretically predict and experimentally demonstrate the spectral flow of a localized mode across a bulk…

Theoretical Polarimetric Channel Characterization of Road Tunnels in Presence of Vehicles at 5.9 GHz

Jose-Maria Molina-Garcia-Pardo, Esteban Egea-Lopez, Martine Lienard, Pierre Degauque

Vehicular communication is a hot topic for developing solutions for automatic guidance, safety-related problems, and end-user applications. The dedicated frequency band in Europe is around 5.9 GHz. Characterization of the communication channel is thus deeply studied especially for the urban and…

Experimental demonstration of nonreciprocal propagation in a piezoelectric phononic crystal with spatio-temporal modulation of electrical conditions

Sarah Tessier, Charles Croënne, Florian Allein, Jerome O. Vasseur, Bertrand Dubus

This work concerns the experimental study of the propagation of elastic waves in a piezoelectric phononic crystal made of several identical piezoelectric elements separated by thin electrodes. We analyze the effect of spatio-temporal modulation of electrical conditions on wave propagation. The…

Asymmetric Elastic Wave Propagation in Spatiotemporally Modulated Nonlinear Granular Phononic Crystal

Florian Allein, Georgios Theocharis, Nicholas Boechler

We study the propagation of transverse-rotational waves in a granular crystal in which the shear stiffnesses are spatiotemporally modulated by a longitudinal propagating wave. Asymmetric wave propagation is investigated as well as one-way conversion and transmission. The combination of different…

On the application of periodic electrical boundary conditions as a means of achieving tunable RF SAW devices

Ricardo Alcorta Galván, Charles Croënne, Bertrand Dubus, Brigitte Loiseaux, Etienne Eustache, Matthieu Bertrand, Anne-Christine Hladky-Hennion

A single port SAW resonator is designed, due to its simplicity, a method for extracting the reflection coefficient of its mirrors is developed. Through this method, the mirror response as a function of different periodic electrical boundary conditions is studied and tunable Bragg band gaps as well…

Manipulation of sonic waves by a quadruple set of Helmholtz resonators

R. Sabat, Yan Pennec, Gaëtan Lévêque, E. Cochin, D. Torrent, Bahram Djafari-Rouhani

This paper examines the coupling effect between Helmholtz resonators (HRs) on mitigating low-frequency sound, using the finite element model. Previously, we highlighted the physical mechanism behind double coupled HRs, generating two resonance modes, symmetric and antisymmetric. Such coupling…

ROOM: Adversarial Machine Learning Attacks Under Real-Time Constraints

Amira Guesmi, Khaled Khasawneh, Nael Abu-Ghazaleh, Ihsen Alouani

Advances in deep-learning have enabled a wide range of promising applications. However, these systems are vulnerable to adversarial attacks; adversarially crafted pertur-bations to their inputs could cause them to misclassify. Most state-of-the-art adversarial attack generation algorithms focus…

Lightweight sound-absorbing metastructures with perforated fish-belly panels

Yabin Jin, Yilong Yang, Zhihui Wen, Liangshu He, Yu Cang, Bin Yang, Bahram Djafari-Rouhani, Yong Li, Yan Li

We propose a perforated metastructure combining fish-belly panels and a corrugated sandwich structure for broadband sound absorption. The curved panels provide a new degree of freedom for sound absorption while the sandwich structure ensures a very good mechanical strength. We develop an effective…

Sensitivity analysis of residuals for soft fault monitoring in Y-shaped networks

Abdelkarim Abdelkarim, Virginie Degardin, Vincent Cocquempot

Networks, mainly composed of cables, are prone to failures. Faults in cables are initially benign (so-called soft faults) and then evolve over time to a much more severe form of faults as short or open circuits (so-called hard faults). It is thus of prime importance to detect and localize…
