Experimental analysis of dense multipath components in an industrial environment

Emmeric Tanghe, Davy Gaillot, M. Lienard, Luc Martens, Wout Joseph

This work presents an analysis of dense multipath components (DMC) in an industrial workshop. Radio channel sounding was performed with a vector network analyzer and virtual antenna arrays. The specular and dense multipath components were estimated with the RiMAX algorithm. The DMC covariance...

[Invited] A phoxonic crystal : photonic and phononic bandgaps in a 1D optomechanical crystal

Jordi Gomis-Bresco, Daniel Navarro-Urrios, Mourad Oudich, Said El-Jallal, Amadeu Griol, Daniel Puerto, Emigdio Chavez, Yan Pennec, Bahram Djafari-Rouhani, Francesc Alzina, Alejandro Martínez, C.M. Sotomayor Torres

Recent years have witnessed the increase of interest in cavity optomechanics, which exploits the confinement and coupling of optical waves and mechanical vibrations at the nanoscale. Amongst the different physical implementations, optomechanical (OM) crystals built on semiconductor slabs would...

A fast and functional technique for the noise figure measurement of differential amplifiers

Yogadissen Andee, Jérôme Prouvée, François Graux, Francois Danneville

This paper presents an original technique to measure the noise figure of differential amplifiers with a four-port network analyzer. The approach is fast and simple as the S-parameters and the output noise powers are measured directly with the analyzer. There is no need of hybrid couplers or baluns...

[Invited Review] SU-8 as a material for lab-on-a-chip-based mass spectrometry

S. Arscott

This short review focuses on the application of SU-8 for the microchip-based approach to the miniaturization of mass spectrometry. Chip-based mass spectrometry will make the technology commonplace and bring benefits such as lower costs and autonomy. The chip-based miniaturization of mass...

RF and broadband noise investigation in high-k/metal gate 28-nm CMOS bulk transistor

Francois Danneville, Laurent Poulain, Yoann Tagro, Sylvie Lepilliet, Benjamin Dormieu, Daniel Gloria, P. Scheer, Gilles Dambrine

In order to pursue Moore's law, material engineering has constituted a real focus during the last decade. In particular, the recent introduction of new Gate stack using High-k dielectrics and Metal Gate (H-k/MG) for CMOS was a key point to downscale the 'Equivalent Oxide Thickness'....

Source localisation in a reverberant plate using average coda properties and early signal strength

Hossep Achdjian, Emmanuel Moulin, Farouk Benmeddour, Jamal Assaad, Lynda Chehami

A statistical reverberation model based on the average distribution of wave packets propagating in a finite plate is described and it is shown that by fitting experimental data to theoretical expressions, either structural or source-related features can be extracted with very few sensors. An...

Characterisation of early HepG2/3a cell response to a microfluidic culture in liver biochips using multi-parametric real time image processing

Marie Naudot, Patrick Paullier, Thomas Dargent, Vincent Senez, Zaher Kharboutly, Isabelle Claude, Eric Leclerc

We developed an image processing protocol to perform time lapse fluorescent analysis in microfluidic biochips. Using three probes to follow three parameters: the number of cell nucleus, the mitochondrial activity and the cell death, we have investigated the behaviour of HepG2/C3a under microfluidic...

Key parameters of silicon micropillar arrays for solar cell performance optimization

Di Zhou, Yan Pennec, Bahram Djafari-Rouhani, Odile Cristini, Tao Xu, Yannick Lambert, Didier Stiévenard

Surface nanostructuration is an important challenge for the optimization of light trapping design in solar cell. We present simulations of the optical properties and efficiency of nanostructured (micropilars-MPs- or nanocones-NCs-) silicon based solar cells as well as measurements of their optical...

We report a 94-GHz large-signal load-pull characterization of InP/GaAsSb double heterojunction bipolar transistors. The investigated devices have an emitter area of 0.20 × 9.5 μm2. Biased for highest power added efficiency (PAE), an output power of 6.62 mW/μm2 (11 dBm), a power gain of 5.2 dB, and...
