Wave propagation in layered piezoelectric rings with rectangular cross sections

Jiangong Yu, Xiaodong Yang, Jean-Etienne Lefebvre

Wave propagation in multilayered piezoelectric structures has received much attention in past forty years. But the research objects of previous research works are almost only for semi-infinite structures and one-dimensional structures, i.e., structures with a finite dimension in only one direction...

Statistical mechanics of holonomic systems as a Brownian motion on smooth manifolds

Fabio Manca, Pierre-Michel Déjardin, Stefano Giordano

The statistical mechanics of arbitrary holonomic scleronomous systems subjected to arbitrary external forces is described by specializing the Lagrange and Hamilton equations of motion to those of the Brownian motion on a manifold. In this context, the Klein-Kramers and Smoluchowski equations are...

Développement d'une technique à double Chirp spatio-temporel basée sur des capteurs SAW-IDT : application à la caractérisation de couches minces et de revêtements fonctionnels, Development of a time-space chirp technique with SAW-IDT sensors : application to the characterization of thin layers, coatings and functional surfaces

Dame Fall

Ce travail rentre dans le cadre de la caractérisation des couches minces, de revêtements et de surfaces fonctionnelles (épaisseur, constantes élastiques,…). Parmi les méthodes de caractérisation potentielles, les méthodes ultrasonores employant des ondes de surface sont particulièrement..., This work is within the scope of characterization of thin layers, coatings and functional surfaces (thickness, elastic constants,…). Among the characterization methods, the ultrasonic methods using surface acoustic waves are particularly interesting. In order to do this, we chose to make use the...

Influence of Doping and Tunneling Interface Stoichiometry on n+In 0.5 Ga 0.5 As/p+GaAs 0.5 Sb 0.5 Esaki Diode Behavior

Salim El Kazzi, A Alireza, Caio Cesar Mendes Bordallo, Quentin Smets, Ludovic Desplanque, Xavier Wallart, Olivier Richard, Bastien Douhard, Anne Verhulst, Nadine Collaert, Clement Merckling, Marc Heyns, Aaron Thean

In this work, we study the influence of molecular beam epitaxy (MBE) growth parameters on the behavior of a staggered band gap n+In 0.5 Ga 0.5 As/p+GaAs 0.5 Sb 0.5 Esaki diodes. We first first show that a careful doping is required to avoid any crystal defects. Then the influence of the doping...

Fabrication et caractérisation d'un réseau de transducteurs piézoélectriques prototype pour application en imagerie médicale

Abdelmajid Bybi, Nadia El Atlas, Mohammed Garoum, Hilal Drissi, Anne-Christine Hladky, Sébastien Grondel

Whether in non-destructive testing or in medical applications, ultrasonic imaging systems have become increasingly used nowadays. Their applications continue to expand and good performances are needed to improve the quality of the diagnosis. Moreover, significant progress has been made since these...

Gradient Index Devices for the Full Control of Elastic Waves in Plates

Yabin Jin, Daniel Torrent, Yan Pennec, Yongdong P Pan, Bahram Djafari-Rouhani

In this work, we present a method for the design of gradient index devices for elastic waves in plates. The method allows the design of devices to control the three fundamental modes, despite the fact that their dispersion relation is managed by different elastic constants. It is shown that by...

Register file reliability enhancement through adjacent narrow-width exploitation.

Hamzeh Ahangari, Ihsen Alouani, Özcan Özturk, Smail Niar, Atika Rivenq

Due to the increasing vulnerability of CMOS circuits, new generations of microprocessors require an inevitable focus on reliability issues. As the Register File (RF) constitutes a critical element within the processor pipeline, it is mandatory to enhance the RF reliability to develop fault tolerant...
