2 W / mm power density of an AlGaN/GaN HEMT grown on free-standing GaN substrate at 40 GHz

Mohamed-Reda Irekti, Marie Lesecq, N. Defrance, Etienne Okada, Eric Frayssinet, Yvon Cordier, Jean-Guy Tartarin, Jean-Claude de Jaeger

In this letter, a record performance at 40 GHz obtained on AlGaN/GaN high electron mobility transistor (HEMT) grown on Hydride Vapor Phase Epitaxy (HVPE) Free-Standing GaN substrate is reported. An output power density of 2 W.mm-1 associated with 20.5 % power added efficiency and a linear power…

[Invited] Hydrogels and Other Ionic Conductors in ‘Piezo-Ionic’ Sensors, Actuators and Electrochemical Devices

John D.W. Madden, Yuta Dobashi, Mirza Sarwar, Dickson Yao, Saeedeh Ebrahimi Takalloo, Claire Preston, Tan Ngoc Nguyen, Justin Wyss, Bertille Dupont, Yael Petel, Carl Michal, Cedric Plesse, Giao Tran-Minh Nguyen, Frederic Vidal, Eric Cattan, Sébastien Grondel, David Shepherd, Geoffrey Spinks

Ionic conductors offer exciting device possibilities, particularly with the advent of highly extensible and easily synthesized hydrogels. Following on from recent work on hydrogel “ionic skin”, ‘piezo-ionic’ sensors and ionic artificial muscle, we present example ionic devices, including…

Stationarity analysis of V2I radio channel in a suburban environment

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

Due to rapid changes in the environment, vehicular communication channels no longer satisfy the assumption of wide-sense stationary uncorrelated scattering. The non-stationary fading process can be characterized by assuming local stationarity regions with finite extent in time and frequency. The…

Molecular characterization of Cryptosporidium isolates from diarrheal dairy calves in France

Mohamed Mammeri, Aurélie Chevillot, Ilham Chenafi, Myriam Thomas, Christine Julien, Isabelle Vallée, Bruno Polack, Jérôme Follet, Karim Tarik Adjou

Cryptosporidium is an obligate intracellular protist parasite infecting a wide range of vertebrate hosts and causes significant intestinal disease in both animals and humans, as some species are zoonotic. Cattle and especially calves have been identified as one of the most common reservoirs of this…

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…
