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...

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'...

A Unified Explanation of gm /ID -Based Noise Analysis

Jack Ou, Pietro Maris Ferreira

We present an unified explanation of the transconductance-to-drain current (gm/ID)-based noise analysis in this paper. We show that both thermal noise coefficient (γ) and device noise corner frequency (fco) are dependent on the gm/ID of a transistor. We derive expressions to demonstrate the...

When capacitive transduction meets the thermomechanical limit: Towards femto-newton force sensors at very high frequency

S. Houmadi, Bernard Legrand, J.P. Salvetat, B. Walter, E. Mairiaux, J.P. Aime, D. Ducatteau, P. Merzeau, L. Buisson, J. Elezgaray, Didier Theron, Marc Faucher

We show that the capacitive transduction of a MEMS device using a setup based on a microwave detection scheme achieves the measurement of the thermomechanical noise spectrum of a high-frequency (>10 MHz) high-stiffness (>10 5 N/m) resonator, reaching the outstanding displacement resolution of...

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...
