Modal analysis and harmonic response of resonators : an extension of a mapped orthogonal functions technique

L. Elmaimouni, Jean-Etienne Lefebvre, F.E. Ratolojanahary, A. Raherison, Tadeusz Gryba, Julien Carlier

A mapped orthogonal functions technique is extended for solving three-dimensional acoustical wave problems with taking into account electrical sources. For validation and illustration purposes, it is applied to the determination of the frequency spectrum of a piezoelectric disc resonator.…

Epitaxial GaAs for X-ray imaging

G. C. Sun, R. Rao, S. Makham, J. C. Bourgoin, X. Y. Zhang, R. Gohier, F. Masiello, J. Haertwig, J. Baruchel, C. Ponchut, Andrea Balocchi, Xavier Marie, O. Gilard, Isabelle Roch-Jeune, J. C. Pesant

To be used for X-ray imaging, semiconductor materials must exhibit good and uniform electronic properties. Epitaxial layers are therefore better adapted than bulk materials which contain dislocations, precipitates and point defects in variable concentrations depending on the growth mode and the…

Phase change memory as synapse for ultra-dense neuromorphic systems: application to complex visual pattern extraction

Manan Suri, Olivier Bichler, Damien Querlioz, Olga Cueto, Luca Perniola, Véronique Sousa, Dominique Vuillaume, Christian Gamrat, Barbara Desalvo

We demonstrate a unique energy efficient methodology to use Phase Change Memory (PCM) as synapse in ultra-dense large scale neuromorphic systems. PCM devices with different chalcogenide materials were characterized to demonstrate synaptic behavior. Multi-physical simulations were used to interpret…

Tunability of aluminum nitride acoustic resonators: a phenomenological approach

Emmanuel Defay, Nizar Ben Hassine, Patrick Emery, Guy Parat, Julie Abergel, Arnaud Devos

A phenomenological approach is developed to identify the physical parameters causing the dc-voltage-induced tunability of aluminum nitride (AlN) acoustic resonators, widely used for RF filters. The typical resonance frequency of these resonators varies from 2.038 GHz at -200 V to 2.062 GHz at +200…

Propagation d'ondes acoustiques dans les milieux à forte porosité, Propagation of acoustic waves in a strong porosity media

Georges Freiha

The essential work of this thesis is the characterization of the elastic coefficients of a porous medium using ultrasonic waves. A bibliographic study is presented at the beginning of the thesis summarizing previous works in this domain, particularly about propagation models of elastics waves.…, Le travail présenté dans cette thèse porte essentiellement sur la caractérisation des constantes élastiques de la matrice poreuse d’un milieu poreux à porosité ouverte par ondes ultrasonores. Une étude bibliographique présente une synthèse des travaux réalisés dans ce domaine, plus particulièrement…
