Acoustic microscope based on magneto-elastic wave phase conjugator

Andrey Brysev, Leonid Krutyansky, Philippe Pernod, Vladimir Preobrazhensky

Acoustic C-scan imaging (acoustic microscopy) by means of supercritical parametric wave phase conjugation (WPC) is studied experimentally. A phase conjugator based on a magneto-acoustic active material is used for compensating phase distortions introduced by solid and polymer aberration layers…

Détection de failles par méthodes sismiques lors du creusement des tunnels, Seismic techniques to detect faults when driving tunnels

Benoit Celse, Bernard Vayssade, Jean Pierre Henry, Philippe Côte, O. Abraham, Bogdan Piwakowski

L'objectif de cet article est de présenter une nouvelle méthode de reconnaissance à l'avancement. Le but est la caractérisation tridimensionnelle du massif en avant du front de taille par méthodes sismiques. La tomographie réflexion a été choisie car elle permet d'obtenir, « en temps…, A new tunnel heading survey method is presented which uses seismic techniques to characterize in three dimensions the rock in front of the tunnel face. The technique of reflection tomography was selected as this provides a high resolution "real-time" map of wave velocities in the rock. lt…

Method for tight-binding parametrization : application to silicon nanostructures

Yann-Michel Niquet, Christophe Delerue, Guy Allan, Michel Lannoo

We propose a method for tight-binding parametrization, designed to give accurate results in the calculation of confined edge states in semiconductor nanostructures of any size. Indeed, this improved tight-binding description accurately reproduces the bulk effective masses as well as the overall…

Sub-harmonic excitation of a planar magneto-mechanical system by means of giant magnetostrictive thin films

Nicolas Tiercelin, Vladimir Preobrazhensky, Philippe Pernod, Henri Le Gall, Jamal Ben Youssef

In the present paper, we report the first results concerning the studies on non-linear actuation of cantilevers using giant magneto-strictive thin films in the vicinity of the spin reorientation transition (SRT). Bimorph centimetre beams (24×5 mm2) were designed using 160 μm thick glass, and 0.4 μm…
