A GaN Schottky diode-based analog phase shifter MMIC

Chong Jin, Etienne Okada, Marc Faucher, Damien Ducatteau, Mohammed Zaknoune, Dimitris Pavlidis

A GaN Schottky Diode-based Analog Phase Shifter MMIC of T-topology has been designed for 35 GHz operation. An all E-Beam technology was employed for MMIC realization. The measured, as well modeled small and large-signal diode characteristics were used for evaluating the phase-shifter performance in...

Impact of spacing between array elements on the performances of diversity schemes in tunnels

M. Lienard, Jose-Maria Molina-Garcia-Pardo, C. Sanchis-Borras, Pierre Degauque

To increase channel capacity in tunnels, MIMO seems to be a promising technique despite the low angular spread of the rays. Indeed, for transmitting frequencies on the order or larger than 1 GHz, the tunnel behaves as an oversized waveguide and the concept of spatial diversity can be replaced by...

Transmission and attenuation of Lamb waves through a periodic array of rectangular slits in a plate

Rayisa P. Moiseyenko, Yan Pennec, Rémi Marchal, Bernard Bonello, Bahram Djafari-Rouhani

Acoustic wave transmission through sub-wavelength slits or holes, then on layers of periodically spaced cylinders and double fishnet structures, known as acoustic metamaterials has been studied in many works in relation with physical phenomena such as extraordinary resonant transmission, sound...

Theory and simulation of optomechanical effects in phoxonic crystals

Said El-Jallal, Mourad Oudich, Yan Pennec, Abdelkader Makhoute, Jordi Gomis-Bresco, Daniel Navarro-Urrios, Clivia M. Sotomayor Torres, Alejandro Martínez, Bahram Djafari-Rouhani

Phoxonic crystals are periodic structures that can exhibit dual phononic and photonic band gaps, thus allowing the simultaneous confinement of both acoustic and optical waves inside the same defect such as a cavity or a waveguide. Then, one can expect an enhancement of the phonon-photon interaction...

Tailoring thermal conductivity of graphene via defect-and-molecular engineering

Stefan Bringuier, J.F. Robillard, Pierre Deymier, Krishna Muralidharan

The exceptional thermal properties of graphene have attracted enormous interest over the past decade. Consequently, there is an increased push towards utilizing graphene in thermal-management systems such as thermal interface materials and thermoelectrics. While, many recent investigations have...

CIGSe absorber layers deposition by single target magnetron sputtering

R. Meunier, S. Fabert, M. Ricci, P.Y. Thoulon, Thomas Aviles, Jean-Pierre Vilcot, Alain Lafond, Michèle Carette, Pierre-Yves Jouan, Marie-Paule Besland

In the last decades, the deposition of CIGSe thin films by sputtering has seldom been investigated. Besides, the sputtering of a single quaternary CIGSe target would be a real advantage for industrial development. Indeed, sputtering technique exhibits a good compatibility with industrial up-scaling...

Synthesis and electrical conductivity of multilayer silicene

Patrick Vogt, Pierre Capiod, Maxime Berthe, Andrea Resta, Paola de Padova, Thomas Brühne, Guy Le Lay, B. Grandidier

The epitaxial growth and the electrical resistance of multilayer silicene on the Ag(111) surface has been investigated. We show that the atomic structure of the first silicene layer differs from the next layers and that the adsorption of Si induces the formation of extended silicene terraces...
