Electrical method for crosstalk cancellation in transducer arrays

Abdelmajid Bybi, Christian Granger, Sébastien Grondel, Anne-Christine Hladky, Jamal Assaad

In this paper, we report a new and simple electrical method to cancel crosstalk in the acoustical arrays. This solution has several advantages compared with that proposed in a previous paper (Bybi et al 2013) [17] where adapted electrical voltages were applied to each neighboring element of the...

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...

Microscopie champ proche micro-ondes pour la caractérisation de liquides

Sijia Gu, Kamel Haddadi, Tuami Lasri

Une plate-forme de microscopie champ proche micro-ondes pour la caractérisation de liquides est proposée. La technique est basée sur l'association d'un analyseur de réseau micro-ondes et d'une sonde coaxiale évanescente. Le principe du système proposé est basé sur le développement d...

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...
