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…

Deterministic and experimental indoor mmW channel modeling

Maria-Teresa Martinez-Ingles, Davy Gaillot, Juan Pascual-Garcia, Jose-Maria Molina-Garcia-Pardo, M. Lienard, José-Víctor Rodriguez

This letter presents an extensive multidimensional analysis of line-of-sight (LOS) experimental data and simulations at 60 GHz over a 9-GHz bandwidth. Numerical versions of the measured multiple-input-multiple-output (MIMO) channel transfer functions were obtained with a ray-tracing engine that…

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…

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…

Dual mechanical behaviour of hydrogen in stressed silicon nitride thin films

F. Volpi, M. Braccini, Arnaud Devos, G. Raymond, A. Pasturel, Pascal Morin

In the present article, we report a study on the mechanical behaviour displayed by hydrogen atoms and pores in silicon nitride (SiN) films. A simple three-phase model is proposed to relate the physical properties (stiffness, film stress, mass density, etc.) of hydrogenated nanoporous SiN thin films…

[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.…

Enhancement of energy storage in epitaxial PbZrO3 antiferroelectric films using strain engineering

Jun Ge, Denis Remiens, Xianlin Dong, Ying Chen, Jean Costecalde, Feng Gao, Fei Cao, Genshui Wang

We demonstrate an approach to enhance the energy storage density W of antiferroelectric film through simple altering a crystallographic orientation of the substrate. We reveal that the antiferroelectric phase stability of PbZrO3 can be enhanced for the (110) or (111) SrTiO3 substrate orientation,…

Atomic scale simulation of Si/SiO2 boundary conductance

Pierre-Arnaud Francioso, Pier Luca Palla, Evelyne Lampin, Fabrizio Cleri

Poor heat dissipation in Si-based nanodevices is an issue for their development. Most of these nanodevices are fabricated using SOI to benefit from the electrical isolation between devices provided by the burried oxyde (BOX). The top silicon layer is also easily processed to form the nanostructure…

Pre-processing technique for increasing localization reliability in non line of sight scenario in non cooperative mode

Isabelle Vin, Davy Gaillot, Pierre Laly, M. Lienard

Accurate localization of mobile phone users is needed for search and rescue applications or for electronic surveillance in urban or suburban areas. Assuming that the mobile station (MS) has been roughly localized by the cellular network or by any other means, we propose an approach using a single…

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…
