Estimation of 60-GHz channels based on energy detection

Stephane Mebaley-Ekome, Laurent Clavier, Antoine Frappé, Eric Pierre Simon, Ilias Sourikopoulos

Estimation of time-varying channels is a common challenge for receiver architectures in wireless communications. Coherent receivers may require good knowledge of the channel impulse response for demodulation of the received symbols, after equalization of a dense multipath channel. However, very few...

Highly tunable Fabry-Perot resonators using piezoelectric phononic crystals

Bertrand Dubus, Marie -Fraise Ponge, Anne-Christine Hladky, Jerome O. Vasseur, Mai Phamthi

Theoretical and experimental analyses of piezoelectric stacks submitted to periodical electrical boundary conditions via electrodes, are conducted. These structures are shown to exhibit Bragg band gaps which are switched on or off by setting electrodes in short or open circuit. Band gap frequency...

Silicon-microtube scaffold decorated with anatase TiO2 as a negative electrode for a 3D litium-ion microbattery

Etienne Eustache, Pascal Tilmant, Laurence Morgenroth, Pascal Roussel, Gilles Patriarche, David Troadec, Nathalie Rolland, Thierry Brousse, Christophe Lethien

An optimized scaffold based on silicon microtubes is designed to increase the surface capacity of 3D lithium-ion microbatteries. High-depth, mechanically robust microstructures are fabricated using microelectronic facilities. Conformal deposition of anatase TiO2 is achieved using atomic layer...
