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...

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...

[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....

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...

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...

Synthesis and characterization of BNT thin films

Sara Abou Dargham, Jihane Jabbour, Youssef Zaatar, Jamal Assaad, Antonio Khoury, Denis Remiens, Doumit Zaouk

Polycrystalline piezoelectric lead-free Bi0.5Na0.5TiO3 (abbreviated as BNT) thin films were deposited on glass substrates by an optimized Sol-Gel process using the Electrospray technique. X-ray Diffraction (XRD) analysis showed that after heating the films at 650˚C for 1 hour, dense and well...

Polymer based flapping-wing robotic insect : progress in design, fabrication and characterization

Alexandre Bontemps, Thomas Vanneste, Caroline Soyer, Jean-Bernard Paquet, Sébastien Grondel, Eric Cattan

In the last decade, many researchers pursued the development of tiny flying robots inspired by natural flyers destined for the exploration of confined spaces, for example. Within this context, our main objective is to devise a flying robot bioinspired from insect in terms of size and wing...

Electrical characterization of semiconductor nanowires by scanning tunneling microscopy

Corentin Durand, Pierre Capiod, Maxime Berthe, Tao Xu, Jean-Philippe Nys, Renaud Leturcq, Philippe Caroff, B. Grandidier

In order to understand the structural and electronic properties of semiconductor nanowires, scanning tunneling microscopy is an appealing technique that can supplement transmission electron microscopies and conventional electrical characterization techniques. It is able to probe the surface of...

Electrical and chemical studies on Al2O3 passivation activation process

Matthieu Pawlik, Jean-Pierre Vilcot, Mathieu Halbwax, D. Aureau, A. Etcheberry, A. Slaoui, T. Schutz-Kuchly, R. Cabal

Passivation process is a key feature to improve the efficiency of silicon solar cells. So far, a 20nm-thick layer of Al2O3 grown by Plasma Enhanced Atomic Layer Deposition (PE-ALD) followed by a 450°C anneal during 15 to 30 min gives the best results in surface carrier recombination velocities on p...
