Acoustic microscopy measurement of elastic constants by using an optimization method on measured and calculated SAW velocities : effect of initial Cij values on the calculation convergence and influence of the LFI transducer parameters on the determination of the SAW velocity

Michael Lematre, Youssef Benmehrez, G. Bourse, Wei-Jiang Xu, Mohamed Ourak

The determination of elastic constants in anisotropic solids by line-focus acoustic microscopy (LFAM) is discussed. The velocity of leaky surface acoustic waves (SAWs) has been obtained for different directions of propagation (φ) from the V(z) curves. The elastic constants are determined from the…

Influence of the microstructure and of an ION beam etching on the domain propagation in PZT thin films

Brice Gautier, Caroline Soyer, Eric Cattan, Denis Remiens, Jean-Claude Labrune

PbZrTiO 3 (PZT) thin films have been grown by RF-magnetron sputtering and sputter etched by Argon ion beam. The topography of the bombarded material is studied by Atomic Force Microscope (AFM), several ferroelectric domains are created by applying a sufficiently high voltage between the tip of the…

Performance of DS-CDMA on the 60 GHz channel

Laurent Clavier, M. Fryziel, Christelle Garnier, Yves Delignon, David Boulinguez

The goal of the paper is to show that a Gaussian approximation can be used to model the global noise in a DS-CDMA system on a 60 GHz frequency band. We show that this approximation can also include the noise due to multipath and to imperfections in power control. The model can then be used as a…

Etude et amélioration d'un récepteur pour la norme EDGE, Study and improvement of a receiver for edge standard

Iyad Dayoub

Le but que nous avons poursuivi dans ce travail est l'amélioration des performances des récepteurs destinés au système EDGE. Nous avons développé plus particulièrement deux points : la reconnaissance automatique du type de modulation dans la rafale en cours de réception et l'égalisation…, The purpose, which we pursued in this work, is the improvement of the performances of the receivers intended for the system EDGE. We developed more particularly two points: The automatic recognition of modulation type in the received burst and the channel equalizer. As regards the modulation type…

Rayonnement et diffusion acoustique en régime impulsionnel sur cibles élastiques immergées : étude par visualisation ultra-rapide et modélisations numériques, Acoustic pulse scattering at water-immersed elastic targets : study by high-speed visualization system and numerical simulation

Laurent Derbesse

Deux outils originaux, l'un expérimental et l'autre numérique, ont été proposés pour l'investigation des phénomènes de diffusion acoustique sur cibles élastiques immergées. Utilisés conjointement, ils fournissent un éclairage nouveau et complémentaire de ces phénomènes relativement…, 2 original tools, experimental and numerical, are proposed for the investigations of acoustic scattering phenomena on water-immersed elastic targets. They supply a new and additional lighting of these phenomena with regard to the conventional methods. They allow the emphasis of the mechanisms of…
