Competing Activities in Social Networks

Mohamed Moez Belhaj, Frédéric Deroïan

We consider a society in which each agent has one unit of a resource to allocate between two activities. Agents are organized in a social network, and each activity generates complementarities between neighbors. We find multiplicity of equilibrium for high intensity of interaction, and we...

Interferometric technique for scanning near-field microwave microscopy applications

Hind Bakli, Kamel Haddadi, Tuami Lasri

An interferometric technique for scanning near-field microscopy applications is proposed. The method is based on the association of a vector network analyzer, an evanescent microwave coaxial probe and a precise interferometer built up with a power divider, a phase-shifter, and an attenuator....

Optical properties of gallium nitride heterostructures grown on silicon for waveguiding application

Irma Saraswati, Arnaud Stolz, S. Ko, El Hadj Dogheche, Nji Raden Poespawati, Retno Wigajatri, Didier Decoster

Gallium nitride (GaN) on silicon (Si) is governed by the possibility to use this family of semiconductor for novel optoelectronic devices. GaN layers are deposited by MOCVD on silicon Si (111) using AlGaN buffer layer. We have studied the microstructure quality of the films. From SEM, TEM and AFM...

Phononic crystals patterning by e-beam lithography "dots on the fly" methodology for integration into thermoelectric energy converters

Valeria Lacatena, Maciej Haras, J.F. Robillard, Stéphane Monfray, Thomas Skotnicki, Emmanuel Dubois

A phononic engineered pattern is conceptualized and realized to hinder the phonons propagation and reduce the lattice thermal conductivity. The pattern fabrication methodology is shown and the procedure of integration on suspended membrane for thermal conductivity characterization is depicted. The...

Broadband sound shielding of Lamb waves through a periodic array of junctions

R.P. Moiseyenko, Yan Pennec, R. Marchal, B. Bonello, Bahram Djafari-Rouhani

We study theoretically sub-wavelength physical phenomena such as resonant transmission and broadband sound shielding for Lamb waves propagating in an acoustic metamaterial made of a thin plate drilled with one or two row(s) of rectangular holes. One of the main results is the demonstration of a...

Experimental investigation of the characteristics of the electromagnetic reverberation in the UWB bands

Aliou Bamba, Wout Joseph, Emmeric Tanghe, Luc Martens, Davy Gaillot, M. Lienard, Jose-Maria Molina-Garcia-Pardo, Maria-Teresa Martinez-Ingles

The electromagnetic reverberation time characteristics are investigated at UltraWide Band (UWB) frequencies, i.e., from 2 to 10 GHz. The reverberation time is bandwidth independent and decreases as the frequency increases. Besides, the reverberation ratio - the contribution of the diffuse fields in...

Multiuser phase coded costas signals with improved cross-correlation and partial cross-ambiguity properties

Nadjah Touati, Charles Tatkeu, Atika Rivenq, Thierry Chonavel

Costas codes are a variant of frequency hopping codes that achieve the «thumbtack» auto-ambiguity function needed in radar applications. However, they may show poor cross- ambiguity properties when selected and assigned randomly which makes them poorly adapted to multiuser radar applications. In...

0.2-μm InP/GaAsSb DHBT power performance with 10 mW/μm² and 25% PAE at 94 GHz

Mohammed Zaknoune, Etienne Okada, Estelle Mairiaux, Yannick Roelens, Damien Ducatteau, Peter Frijlink, Marc Rocchi, Hassan Maher

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...
