Near-field Microwave Microscopy for Liquid Characterization

Sijia Gu, Kamel Haddadi, Tuami Lasri

A near-field microwave microscopy platform for the characterization of liquids is proposed. The technique is based on the association of a network analyzer and an evanescent microwave coaxial probe. The major feature of the system proposed is the development of a broadband tunable matching network...

Theoretical and experimental investigation of Lamb waves characteristics in AlN/TiN and AlN/TiN/NCD composite membranes

Ali Soltani, Abdelkrim Talbi, J-C Gerbedoen, Jean-Claude de Jaeger, Philippe Pernod, V. Mortet, A. Bassam

In this study, we present a theoretical and experimental investigations of the zero order quasi-symmetric (S0) Lamb waves mode propagating in AlN/TiN and AlN/TiN/NCD composite membranes. Theoretical analysis of S0 mode characteristics shows that The AlN/TiN membrane enables to achieve smooth...

A study on the effect of wire bonding interconnects of BCB capped CPW to CPW on LTCC substrate

Seonho Seok, Janggil Kim, Markku Lahti

The effect of wire bonding interconnects between BCB capped CPW on silicon chip and CPW on low temperature cofired ceramic (LTCC) package is presented. The Si chip is attached onto LTCC package using conductive silver epoxy. Two different bond wires, ribbon-wire and normal wire are used for the...

Multiple-Antenna Based Blind Spectrum Sensing in the Presence of Impulsive Noise

Kais Hassan, Roland Gautier, Iyad Dayoub, Marion Berbineau, Emanuel Radoi

Cognitive radio was proposed as a solution to the spectrum scarcity problem. One of the basic functions of any cognitive radio is the spectrum sensing. Most of the existing works on spectrum sensing consider the Gaussian noise assumption. In practice, this assumption is not always valid since...

Gas recovery potential of sandstones from tight gas reservoirs

Z. Duan, C.A. Davy, F. Agostini, L. Jeannin, David Troadec, F. Skoczylas

The aim of our experimental study is to characterize experimentally the petro-physical properties of a set of sandstones originating from different depths from a single tight gas ﬁeld, in order to improve our knowledge on their gas recovery potential. The initial characterization of these...

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...
