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...

Multi-carrier transmission of vectorial modulation schemes using electronic transceivers at 588 GHz

Guillaume Ducournau, P. Szriftgiser, D. Bacquet, Mohammed Zaknoune, Rédha Kassi, Jean-Francois Lampin

A reported is presented on the first communication system using vectorial modulation schemes above 500 GHz. Using Schottky-based electronic technologies at 588 GHz, potentialities of high-level multicarrier modulation schemes for wireless links are analysed. The wireless link is composed of an...

Guided waves in multilayered plates

Jiangong Yu, Jean-Etienne Lefebvre, Lahoucine Elmaimouni

Conventional orthogonal polynomial approach can solve the multilayered plate only when the material properties of two adjacent layers do not change significantly. This paper developed an improved orthogonal polynomial approach to solve wave propagation in multilayered plates with very dissimilar...

Young's modulus extraction of epitaxial heterostructure AlGaN/GaN for MEMS application

Achraf Ben Amar, Marc Faucher, Virginie Brandli, Yvon Cordier, Didier Theron

This paper presents a Young's modulus extraction method for thin film group III-nitrides materials such as GaN, AlN, and its ternary AlGaN. The AlGaN/GaN heterostructures are grown by molecular beam epitaxy on Si (111) substrate and designed for MEMS applications. Various cantilevers with a...

High-gain Yagi-Uda antenna on cyclic olefin copolymer substrate for 300 GHz applications

Fabio Pavanello, Guillaume Ducournau, Emilien Peytavit, Sylvie Lepilliet, Jean-Francois Lampin

The cyclic olefin copolymer is a dielectric material with very attractive mechanical and electrical properties for millimeter- and submillimeter-based devices as recently demonstrated in a few applications. Here, we present the possibility of employing this material as a substrate for traveling-...

Gold-free ternary III-V antimonide nanowire arrays on silicon : twin-free down to the first bilayer

Sònia Conesa-Boj, Dominik Kriegner, Xiang-Lei Han, S.R. Plissard, Xavier Wallart, Julian Stangl, Anna Fontcuberta I Morral, Philippe Caroff

With the continued maturation of III-V nanowire research, expectations of material quality should be concomitantly raised. Ideally, III-V nanowires integrated on silicon should be entirely free of extended planar defects such as twins, stacking faults, or polytypism, position-controlled for...

Micro-nanostructured silicon based superomniphobic surfaces

Thi Phuong Nhung Nguyen, Rabah Boukherroub, V. Thomy, Yannick Coffinier

We report on the fabrication of silicon nanostructured superhydrophobic and superoleophobic surfaces also called "superomniphobic" surfaces. For this purpose, silicon interfaces with different surface morphologies, single or double scale structuration, were investigated. These structured...

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...
