A tiny gas-sensor system based on one-dimensional photonic crystal

Afaf Bouzidi, Driss Bria, Abdellatif Akjouj, Yan Pennec, Bahram Djafari-Rouhani

We present a gas monitoring system for detecting the gas concentration in ambient air. This sensor is based on a 1D photonic crystal formed by alternating layers of magnesium fluoride (MgF2) and silicon (Si) with an empty layer in the middle. The lamellar cavity (defect layer) will be filled with…

Prediction of robust two-dimensional topological insulators based on Ge/Si nanotechnology

Christophe Delerue

Atomistic tight-binding calculations show that two-dimensional topological insulators can be obtained using Ge or Ge/Si nanotechnologies. The strong quantum confinement is used to open energy gaps in the valence band of artificial graphene made of Ge. These gaps are topologically nontrivial due to…

Characterization of Micrometric and Localised Residual Stresses on Amorphous Materials Using Dispersion of Surface Acoustic Waves

Marc Duquennoy, Mohammadi Ouaftouh, Julien Deboucq, Jean-Etienne Lefebvre, Frédéric Jenot, Mohamed Ourak

For amorphous materials such as glass, the fragility of the material can be limited using surface reinforcement by chemical tempering. The principle of chemical tempering consists in forming a superficial compression layer on the surface by immersing the glass in a solution of molten potassium…

Theoretical study and 2D computational modeling of middle-infrared radiation generation in the field of few-cycle laser pulse propagating in GaSe slab waveguide

David Hovhannisyan, E Laziev, Samuel Dupont, G Hovhannisyan

We have performed the theoretical study and 2D finite-difference time-domain-based computational modeling of middle-infrared radiation generation in the field of few-cycle laser pulse propagating in GaSe slab waveguide. The interaction of linearly polarized pulse with 1.98 um central wavelength, 22…

Simplified Random-Walk-Model-Based Kalman Filter for Slow to Moderate Fading Channel Estimation in OFDM Systems

Huaqiang Shu, Laurent Ros, Eric Pierre Simon

This study deals with multi-path channel estimation for orthogonal frequency division multiplexing systems under slow to moderate fading conditions. Advanced algorithms exploit the channel time-domain correlation by using Kalman Filters (KFs) based on an approximation of the time-varying channel.…

Uncertainties assessment of noise parameters in D- band using in situ tuner techniques

Marina Deng, Daniel Gloria, Thomas Quémerais, Pascal Chevalier, Sylvie Lepilliet, Francois Danneville, Gilles Dambrine

When transistor noise characterization becomes a difficult task at millimeter wave range, the accuracy on the resulting noise parameters is not or poorly discussed. Within this context, this paper aims to present a methodology to estimate the uncertainties related to the extraction of the four…
