On the contribution of dense multipath components in an intrawagon environment for 5G mmW massive MIMO channels

Frédéric Challita, Vicent Rodrigo-Penarrocha, Lorenzo Rubio, Juan Reig, Leandro Juan-Llacer, Juan Pascual-Garcia, Jose-Maria Molina-Garcia-Pardo, M. Lienard, Davy Gaillot

In this letter, the dependence of the specular (SMC) and dense multipath components (DMC) to the inter-user spatial correlation and sum-rate capacity of a massive multi-user MIMO (MU-MIMO) setup is evaluated from measurements conducted inside an underground subway wagon at the 25 - 40 GHz candidate…

Measurements of interfacial tension coefficient using excitation of progressive capillary waves by radiation pressure of ultrasound in microgravity

Leonid Krutyansky, Andrey Brysev, Farzam Zoueshtiagh, Philippe Pernod, Dmitrii Makalkin

A method dedicated to the measurement of low surface tension coefficients in binary fluids is proposed. The method which is not intrusive and does not interfere with the volume/weight proportion of liquid composing the binary mixture utilizes excitation of progressive capillary waves by pulsed…

Optomechanics: a key towards next-generation experiments in atomic force microscopy?

Lucien Schwab, Pierre Allain, Didier Theron, Marc Faucher, Benjamin Walter, Sébastien Hentz, Guillaume Jourdan, Ivan Favero, Bernard Legrand

Atomic Force Microscopy (AFM) is a versatile and ubiquitous technique based on a resonating tip probe that interacts with the sample to be analysed in terms of topography and mechanical properties. Next-generation investigations in molecular biophysics like protein folding/unfolding, receptor-…

Heat treatment of commercial polydimethylsiloxane PDMS precursors: Part II. Thermal properties of carbon-based ceramic nanocomposites

Srisaran Venkatachalam, Stéphane Lenfant, Michael Depriester, Abdelhak Hadj Sahraoui, D. Hourlier

Organosilicon polymer-derived ceramic (PDC) materials have been extensively studied for their various properties such as mechanical, chemical and electrical properties. One of the least explored properties of PDC is their thermal properties, required for designing a heat energy converter. In this…

Channel correlation-based approach for feedback overhead reduction in massive MIMO

Frédéric Challita, Pierre Laly, Marwan Yusuf, Emmeric Tanghe, Wout Joseph, Pierre Degauque, M. Lienard, Davy Gaillot

For frequency-division duplex multiple-input-multiple-output (MIMO) systems, the channel state information at the transmitter is usually obtained by sending pilots or reference signals from all elements of the antenna array. The channel is then estimated by the receiver and communicated back to the…

FPGA Implementation of GPS - L5 Adaptive Acquisition

Kamel Benachenhou, Mohamed-Laid Bencheikh, Abdelmalik Taleb-Ahmed

This paper deals with the implementation of an adaptive acquisition stage in a global navigation satellite - GNSS - receiver with a pilot and data channel in case of GNSS L5 signal. Adaptive acquisition decides on GNSS signal presence or absence by comparing a cell under test with an adaptive…

Setting Carriers Free: Healing Faulty Interfaces Promotes Delocalization and Transport in Nanocrystal Solids

Willem Walravens, Eduardo Solano, Filip Geenen, Jolien Dendooven, Oleg Gorobtsov, Athmane Tadjine, Nayyera Mahmoud, Patrick Peiwen Ding, Jacob Ruff, Andrej Singer, Günther Roelkens, Christophe Delerue, Christophe Detavernier, Zeger Hens

Superlattices of epitaxially connected nanocrystals (NCs) are model systems to study electronic and optical properties of NC arrays. Using elemental analysis and structural analysis by in situ X-ray fluorescence and grazing-incidence small-angle scattering, respectively, we show that epitaxial…
