Detection and localization of a defect in a reverberant plate using acoustic field correlation

Lynda Chehami, Emmanuel Moulin, Julien de Rosny, Claire Prada, Olivier Bou Matar, Farouk Benmeddour, Jamal Assaad

Green's function can be retrieved from cross-correlation of a diffuse field generated by noise sources. Today, this important result is the fundamental of several passive imaging techniques. The aim of this paper is to establish the suitability of these methods to detect and locate a defect in...

Nonlinear measurement dedicated to non periodic pulse train for radar power amplifier characterization

Vincent Bridier, Damien Ducatteau, M. Olivier, Hans-Joachim Simon, François Graux, Philippe Eudeline, Gilles Dambrine

A six port mixer based 20GHz nonlinear vector network analyzer (NVNA) dedicated to the characterization of radar power amplifier driven by non periodic pulsed signal is proposed. For the first time a mixer based NVNA is able to measure the fundamental and two harmonics simultaneously while using...

[Invited] Millimeter-wave noise and power characterization using in situ tuner

Thomas Quemerais, Daniel Gloria, Sandrine Oeuvrard, Christophe Gaquière, Francois Danneville, Gilles Dambrine, Marina Deng

The advanced micro-and nano-technologies now allows the design of high frequencies integrated circuit with transistors operating at millimeter-wave (MMW) frequencies and beyond. This evolution led us to develop industrial test tools to characterize and validate the models of these transistors....

Electrooptic and converse-piezoelectric properties of epitaxial GaN/Si structures for optoelectronic applications

Mireille Cuniot-Ponsard, Irma Saraswati, S.-M. Ko, Mathieu Halbwax, Y.-H. Cho, N.-R. Poespawati, El Hadj Dogheche

In order to take advantage in all-optic optoelectronic devices, we have investigated the optical and piezoelectric properties of GaN films deposited on (111) silicon. Films are epitaxially grown by MOCVD, thanks to a buffer made of (Al, Ga) N intermediate layers [1]. Structural properties of GaN...

UWB System Based on the M-OAM Modulation in IEEE.802.15.3a Channel

Khadija Hamidoun, Raja Elassali, Yassin El Hillali, Khalid Elbaamrani, Atika Rivenq, F. Elbahhar

Known for many years but unexploited in the field of communications, ultra wideband systems (UWB) can be a solution to the saturation of the frequency bands. The advantage of such systems is that they are inexpensive in energy because of the limitations imposed by the standard. Our work is to...

Experimental analysis of dense multipath components in an industrial environment

Emmeric Tanghe, Davy Gaillot, M. Lienard, Luc Martens, Wout Joseph

This work presents an analysis of dense multipath components (DMC) in an industrial workshop. Radio channel sounding was performed with a vector network analyzer and virtual antenna arrays. The specular and dense multipath components were estimated with the RiMAX algorithm. The DMC covariance...

Band gap formation and elastic wave transmission in two-dimentional surface phononic crystal

Sergey Yankin, Abdelkrim Talbi, Yu Du, Jean-Claude Gerbedoen, Vladimir Preobrazhensky, Philippe Pernod, Olivier Bou Matar

Using finite element method analysis of surface acoustic wave (SAW) propagation in the phononic crystal in a form of periodic lattice from nickel pillars, located on a piezoelectric substrate of Y+128°-cut LiNbO3, has been conducted. Amplitude and phase characteristics of SAW propagation through...
