Terahertz wireless communication using GaAs transistors as detectors

L. Tohme, S. Blin, Guillaume Ducournau, P. Nouvel, D. Coquillat, S. Hisatake, T. Nagatsuma, A. Pénarier, L. Varani, W. Knap, Jean-Francois Lampin

The detection of high data-rate wireless communication using a terahertz- frequency carrier, and a GaAs transistor as a detector, is reported. Communications are investigated around 0.2 and 0.3087 THz. For the first time, an error-free transmission at data rates up to 8.2 Gbit/s is demonstrated,…

Ingénierie des matériaux artificiels électromagnétiques : cristaux photoniques et métamatériaux

D. Lippens

Le développement des techniques de micro-structuration des matériaux diélectriques et des composés métalliques permet actuellement un contrôle sans précédent de l'interaction des ondes électromagnétiques avec les matériaux artificiels. Nous illustrons ici l'ingénierie de telles structures…

Finite element analysis and experimental study of surface acoustic wave propagation through two-dimensional pillar-based surface phononic crystal

S. Yankin, Abdelkrim Talbi, Y. Du, Jean-Claude Gerbedoen, Vladimir Preobrazhensky, Philippe Pernod, Olivier Bou Matar

We study both theoretically and experimentally the interaction of surface elastic waves with 2D surface phononic crystal (PnC) on a piezoelectric substrate. A rigorous analysis based on 3D finite element method is conducted to calculate the band structure of the PnC and to analyze the transmission…

Sub-THz characterisation of monolayer graphene

Ehsan Dadrasnia, Sujitha Puthukodan, Vinod V. K. Thalakkatukalathil, Horacio Lamela, Guillaume Ducournau, Jean-Francois Lampin, Frédéric Garet, Jean-Louis Coutaz

We explore the optical and electrical characteristics of monolayer graphene by using pulsed optoelectronic terahertz time-domain spectroscopy in the frequency range of 325-500 GHz based on fast direct measurements of phase and amplitude. We also show that these parameters can, however, be measured…

Incertitudes des traitements des lésions hépatiques en radiothérapie stéréotaxique avec asservissement à la respiration

Marie Charoy

Le Centre Oscar Lambret traite avec le Cyberknife®, depuis juin 2007, les lésions hépatiques en conditions stéréotaxiques, avec un asservissement à la respiration par des repères externes corrélés à des grains implantés près de la cible. Les résultats cliniques montrent un excellent contrôle local…

On detection method for soft iterative decoding in the presence of impulsive interference

Vincent Dimanche, Alban Goupil, Laurent Clavier, Guillaume Gelle

This paper deals with the performance improvement of soft iterative decoders in impulsive interference modeled by additive noise. In case of $alpha$-stable noise, the inputs of the belief propagation decoder are too complex to compute. We propose to use an approximation of the log likelihood ratio…

Temperature dependence of dynamic hysteresis behavior in Pb0.4Sr0.6TiO3 ferroelectric films

Kui Li, Tao Li, Gang Du, Denis Remiens, Xianlin Dong, Genshui Wang

The temperature (T) dependence of dynamic hysteresis behavior is investigated in low temperature crystallized Pb0.4Sr0.6TiO3 thin films between 85 K and 340 K. It was found that the temperature scaling relations for hysteresis area 〈A〉, remnant polarization Pr and coercive field Ec take the…

Monte Carlo study of low and high-field electron transport in GaN-based heterostructures

Jean-Luc Thobel, François Dessenne, Christophe Dalle

Electron transport properties of GaN-based heterostructures are investigated by means of a Monte Carlo model, which considers a large number of subbands in several valleys. Room-temperature low-field mobility consistent with experimental results is obtained provided that screening of phonon…

Geometrical optics-based model for dielectric constant and loss tangent free-space measurement

Kamel Haddadi, Tuami Lasri

A microwave free-space reflection method for determining the complex permittivity of planar dielectric materials is demonstrated. The method makes use of the measurement of the near-field microwave reflection coefficient of a metal-backed sample. The modeling of the structure and its calibration…
