Classification and characterization of impulsive noise on indoor power line used for data communications

Virginie Degardin, M. Lienard, A. Zeddam, F. Gauthier, Pierre Degauque

The performance of a link using the indoor power line network as a medium for communication strongly depends on the noise characteristics. Besides the background noise and the narrow band noise mainly due to broadcast transmitters, impulsive noise adversely affects the quality of service. This…

Génération et Propagation aux fréquences Terahertz, Waveguiding and photomixing at Terahertz frequency

Emilien Peytavit

Ce travail de thèse a porté sur la génération aux fréquences THz par la technique dite de photomélange. La première partie de cette étude a été consacrée aux éléments essentiels d'un tel dispositif utilisé au THz : le GaAs épitaxié à basse température (GaAs BT), un photodétecteur à électrodes…, This Thesis deals with the generation of THz frequencies based on the photomixing process. The first part describes the main components of devices, which are low-temperature-grown GaAs (LTG-GaAs), interdigitated electrodes and planar antenna. This study allows us to obtain a largely tunable source…

Concurrent multiscale model of an atomic crystal coupled with elastic continua

P. Deymier, Jerome O. Vasseur

A methodology based on a Green’s function formalism, which enables the coupling between atomic and continuous systems, is employed to evaluate the dynamical properties of concurrent elastic multiscale models. Boundary conditions satisfying the continuity of displacement and stress across interfaces…

High performance double-sided microstrip PBG filter

Tahsin Akalin, Miguel A. G. Laso, E. Delos, Txema Lopetegi, Olivier Vanbésien, Mario Sorolla, Didier Lippens

Microwave filters in microstrip technology have been designed by taking advantage of metal patterning of the front and back-side planes. It is shown that such an approach with drilled holes in the ground plane for the high impedance sections permits one to alleviate some of the drawbacks associated…

High performance HBV multipliers monolithically integrated onto a host quartz substrate

T. David, S. Arscott, J.-M. Munier, Thibaut Decoopman, Tahsin Akalin, Patrick Mounaix, Xavier Mélique, Olivier Vanbésien, Gérard Beaudin, Didier Lippens

Fully integrated monolithic circuits incorporating InP-based heterostructure barrier varactor (HBV) frequency multipliers have been fabricated via epitaxial lift-off and transfer-substrate techniques onto a quartz substrate. We have obtained a maximum output power of 6 mW at 288 GHz corresponding…

Radiothérmométrie micro-ondes

Bertrand Bocquet

La radiométrie est un terme assez large qui désigne la mesure de l’intensité du rayonnement électromagnétique qu’il soit ionisant ou non ionisant. Notre domaine d’intervention se situe au niveau des ondes électromagnétiques non ionisantes, où nous pouvons différencier deux domaines importants : les…

Thermal stability of Pt- and Ni-based Schottky contacts on GaN and Al 0.31 Ga 0.69 N

E. Monroy, F. Calle, R. Ranchal, T. Palacios, M. Verdu, F Sanchez, M Montojo, M. Eickhoff, Franck Omnès, Z. Bougrioua, I. Moerman

In this work we analyse the performance of Pt- and Ni-based Schottky metallizations on AlxGa1−xN (x = 0, 0.31). An intermediate thin Ti layer is shown to enhance the thermal stability of Pt/Au, and leads to an increase of the Schottky barrier height. Pt/Ti/Au contacts on GaN provide a barrier…

Statics and dynamics in giant magnetostrictive Tbx/Fe(1-x)/-Fe0.6Co0.4 multilayers for MEMS

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

In the present paper, giant magnetostric-tive thin films have been investigated for future micro-electromechanical systems (MEMS) purposes. For this goal, flexural and torsional motions have been studied in low field anisotropic giant magnetostrictive (GMS) single domain state (SDS) exchange-…
