Composants pour la génération et la détection d'impulsion térahertz, Components for generating and detecting terahertz pulses

Olivier Offranc

Le domaine de fréquences térahertz fait la liaison entre le monde des transistors et des lasers. Malgré les nombreuses applications possibles, il n'existe pas, à l'heure actuelle, de source térahertz compacte fonctionnant à température ambiante. De même, pour la détection d'…, The terahertz frequency range makes the connection between the world of transistors and lasers. Despite the many potential applications, today there is not compact terahertz source operating at room temperature. Similarly, for detection of terahertz pulses, there is not really satisfying systems…

Numerical simulations for a quantitative analysis of AFM electrostatic nanopatterning on PMMA by Kelvin force microscopy

Etienne Palleau, Laurence Ressier, Lukasz Borowik, Thierry Melin

Electrostatic nanopatterning of electret thin films by atomic force microscopy (AFM) has emerged as an alternative efficient tool for the directed assembly of nano-objects on surfaces. High-resolution charge imaging of such charge patterns can be performed by AFM-based Kelvin force microscopy (KFM…

Electrowetting and droplet impalement experiments on superhydrophobic multiscale structures

Florian Lapierre, Philippe Brunet, Yannick Coffinier, V. Thomy, Ralf Blossey, Rabah Boukherroub

The reversible actuation of droplets on superhydrophobic surfaces under ambient conditions is currently an important field of research due to its potential applicability in microfluidic lab-on-a-chip devices. We have recently shown that Si-nanowire (NW) surfaces allow for reversible actuation…

100 nm period grating by high-index phase-mask immersion lithography

Yannick Bourgin, Yves Jourlin, Olivier Parriaux, Anne Talneau, Svetlen Tonchev, Colette Veillas, P. Karvinen, Nicolas Passilly, Ahmad Md Zain, R.M. de La Rue, Jurgen van Erps, David Troadec

The interferogram of a high index phase mask of 200 nm period under normal incidence of a collimated beam at 244 nm wavelength with substantially suppressed zeroth order produces a 100 nm period grating in a resist film under immersion. The paper describes the phase mask design, its fabrication,…

Joint Estimation of Carrier Frequency Offset and Channel Complex Gains for OFDM Systems in Fast Time-varying Vehicular Environments

Eric Pierre Simon, Hussein Hijazi, Laurent Ros, Marion Berbineau, Pierre Degauque

In this paper, the physical nature of the radiochannel is considered by using an L-path channel model to developing an algorithm for OFDM systems operating in fast time-varying vehicular environment. Assuming the Time of Arrival (TOA) is known, a novel iterative pilot-aided algorithm for joint…
