Near-field scanning microwave microscope for subsurface non-destructive characterization

Sijia Gu, Kamel Haddadi, Abdelhatif El Fellahi, Tuami Lasri

We report a nondestructive testing system based on near-field scanning microwave microscopy. The instrumentation is built up with a vector network analyzer, a fully automated tuning matching network and an evanescent microwave probe. The system can perform microwave images in the frequency band 0.1…

Time-Frequency Processing Adapted for the Different Electromagnetic Compatibility Issues in the Railway Domain

Mohammed Raouf Kousri, Virginie Deniau, Marc Heddebaut, S. Baranowski, Jean Rioult

The railway environment is very rich in terms of electromagnetic disturbances. The variety of the transient and permanent interferences and the current evolution of the communication and signaling railway systems require the adaptation of EMC railway standards. In particular, standardized emission…, L'environnement électromagnétique du chemin de fer est très riche en termes de perturbations électromagnétiques. La variété des signaux transitoires et des interférences permanentes et l'évolution actuelle des systèmes de communication et de signalisation ferroviaire nécessitent l'…

Ambiguity function and Cramer-Rao bounds for standard and new modified Costas signals

Nadjah Touati, Charles Tatkeu, Thierry Chonavel, Yassin El Hillali, Atika Rivenq

The Cramer-Rao bound (CRB) gives a lower variance bound that an estimator can achieve. Presented is a mathematical approach to estimate it for specific radar signals, namely Costas signals and their modified versions. The modified versions design consists in widening Costas frequency hops and…

Drift velocity versus electric field in < 110 > Si nanowires: Strong confinement effects

Jing Li, Gabriel Mugny, Yann-Michel Niquet, Christophe Delerue

We have performed atomistic simulations of the phonon-limited high field carrier transport in < 110 > Si nanowires with small diameter. The carrier drift velocities are obtained from a direct solution of the non-linear Boltzmann transport equation. The relationship between the drift velocity…

Theoretical and experimental analyses of tunable Fabry-Perot resonators using piezoelectric phononic crystals

Marie-Fraise Ponge, Bertrand Dubus, Christian Granger, Jerome O. Vasseur, Mai Pham Thi, Anne-Christine Hladky

Theoretical and experimental analyses of piezoelectric stacks submitted to periodical electrical boundary conditions via electrodes are conducted. The presented structures exhibit Bragg band gaps that can be switched on or off by setting electrodes in short or open circuit. The band gap frequency…

Characterization of flexible CMOS technology tranferred onto a metallic foil

Justine Philippe, Aurelien Lecavelier Des Etangs-Levallois, Philip Latzel, Francois Danneville, J.F. Robillard, Daniel Gloria, Emmanuel Dubois

In this work we demonstrate a method to transfer high-performance industrial CMOS circuits thinned down to 5.7 mu m and bond onto a 25-mu m-thick stainless steel foil with a 800-nm-thick indium layer. The bonding is performed at the temperature of 100 degrees C with an applied pressure of 1.2 bar.…

Two-frequency excitation of single-mode Faraday waves

William R. Batson, Farzam Zoueshtiagh, Raviprasad Narayanan

The purpose of this work is to investigate, for the first time, excitation of Faraday waves in small containers using two commensurate frequencies. This spatial restriction, which is encountered at low frequencies, leads to a wave composed primarily of one spatial eigenmode of the container. When…

A distributed antenna system for indoor accurate WiFi localization

Christophe Loyez, Michael Bocquet, C. Lethien, N. Rolland

Specific infrastructures are a key challenge for indoor geo-localization systems. In particular, an accurate narrowband localization technique using 802.11 g WiFi signals is proposed in this letter. The related system architecture is built on the basis of radio over fiber topology of distributed…
