R. Malmqvist, R. Jonsson, C. Samuelsson, A. Gustafsson, S. Reyaz, D. Dancila, A. Rydberg, B. Grandchamp, S. Seok, M. Fryziel, P.A. Rolland, P. Rantakari, M. Lahti, T. Vaha-Heikkla, R. Baggen

This paper presents the results of some reconfigurable RF-MEMS switching circuits and antennas fabricated using GaAs MMIC and LTCC based processes. Wafer-level packaged GaAs RF-MEMS series and shunt switches demonstrating low losses (≤0.5 dB) up to 40 GHz are presented together with a compact Ka-...

Time-reversal UWB positioning beacon for railway application

B. Fall, F. Elbahhar, M. Heddebaut, Atika Rivenq

This paper studies a new positioning beacon for railway transport using Ultra Wideband (UWB) radio and Time Reversal (TR) techniques. UWB radio has the potential to offer a good level of performance in terms of localization accuracy. Time Reversal channel pre-filtering facilitates signal detection...

Surface plasmons in coaxial metamaterial cables

M.S. Kushwaha, Bahram Djafari-Rouhani

Thanks to Victor Veselago for his hypothesis of negative index of refraction, metamaterials – engineered composites – can be designed to have properties difficult or impossible to find in nature: they can have both electrical permitivity (ǫ) and magnetic permeability (µ) simultaneously negative....

Guided-wave electro-optic characterization of BaTiO3 thin films using the prism coupling technique

Floriane Leroy, Anthony Rousseau, Sandrine Payan, El Hadj Dogheche, David Jenkins, Didier Decoster, Mario Maglione

Ferroelectric BaTiO3 (BTO) thin films are grown by RF sputtering onto an indium tin oxide bottom electrode on a MgO single-crystal substrate. We have studied here the optical properties by the prism coupling technique. We report the ordinary and extraordinary refractive indices of the films, the...

22 Gbps wireless communication system at 0.4 THz

Guillaume Ducournau, P. Szriftgiser, Fabio Pavanello, Philipp Latzel, Alexandre Beck, Tahsin Akalin, Emilien Peytavit, Mohammed Zaknoune, Denis Bacquet, Jean-Francois Lampin

By combining a lJTC-PD as a THz emitter and a 400 G Hz Schottky-based heterodyne detection, we realized an indoor THz link working up to 22 Gbps at 400 GHz carrier frequency with ultra-low THz power. The eye diagram at receiver is clearly opened are the system is working with only 1 mu W received...

Exploring electronic structure of one-atom thick polycrystalline graphene films : a nano angle resolved photoemission study

J. Avila, I. Razado, S. Lorcy, R. Fleurier, E. Pichonat, D. Vignaud, X. Wallart, M.C. Asensio

The ability to produce large, continuous and defect free films of graphene is presently a major challenge for multiple applications. Even though the scalability of graphene films is closely associated to a manifest polycrystalline character, only a few numbers of experiments have explored so far...

Characteristics of the surface microstructures in thick InGaN layers on GaN

Y. El Gmili, G. Orsal, K. Pantzas, A. Ahaitouf, T. Moudakir, S. Gautier, G. Patriarche, David Troadec, Jean-Paul Salvestrini, A. Ougazzaden

This paper focuses on a comparative study of optical, morphological, microstructural and microcompositional properties of typical InGaN samples which exhibit V-defects but also two additional surface defects features, referred to as inclusion#1 (Ic1) and inclusion#2 (Ic2). HR-XRD, AFM, SEM, STEM...
