Bulk acoustic wave transformer employing periodically polled array of piezoelectric rods

Victor Plessky, Ventsislav Yantchev, C. Granger, Anne-Christine Hladky

Multilayer bulk acoustic wave transformer employing a periodical array of piezoelectric rods with alternating polarization is experimentally demonstrated for the first time. Voltage transformation coefficient in excess of 6 was measured at a frequency of 150kHz, providing thus a solid experimental…

Inverse saffman-taylor experiments with particles lead to capillarity driven fingering instabilities

Ilyesse Bihi, Michael Baudoin, Jason E. Butler, Christine Faille, Farzam Zoueshtiagh

Using air to displace a viscous fluid contained in a Hele-Shaw cell can create a fingering pattern at the interface between the fluids if the capillary number exceeds a critical value. This Saffman-Taylor instability is revisited for the inverse case of a viscous fluid displacing air when partially…

AlN/IDT/AlN/Sapphire SAW Heterostructure for High-Temperature Applications

Ouarda Legrani, Thierry Aubert, Omar Elmazria, Ausrine Bartasyte, Pascal Nicolay, Abdelkrim Talbi, Pascal Boulet, Jaafar Ghanbaja, Denis Mangin

Recent studies have evidenced that Pt/AlN/Sapphire SAW devices are promising for high-temperature high-frequency applications. However, they cannot be used above 700°C in air atmosphere as the Pt interdigital transducers (IDTs) agglomerate and the AlN layer oxidizes in such conditions. In this…

DS-UWB and TH-UWB Energy Consumption Comparison

Adil Elabboubi, Fouzia Elbahhar, Marc Heddebaut, Yassin El Hillali

The energy consumption of the wireless communication systems is starting to be unaffordable. One way to improve the power consumption is the optimization of the communication techniques used by the communication networks and devices. In order to develop an energy efficient UWB multi-user…

Electronic structure investigation of Al0.7Ga0.3As/GaAs nanometric heterostructures by Kelvin force microscopy

Sylvain Pouch, Francois Triozon, Nicolas Chevalier, Thierry Melin, Yann Michel Niquet, Lukasz Borowik

Kelvin force microscopy provides a spatially resolved measurement of the surface potential, which is related to the energetic band structure of a material. The goal of this work is to investigate the surface potential on Al0.7Ga0.3As and GaAs heterostructures with a decreasing layer thickness up to…

Broadband dielectric characterization of aqueous saline solutions by an interferometer-based microwave microscope

S. Gu, Tianjun Lin, T. Lasri

The complex dielectric permittivity of aqueous saline solutions has been determined in the frequency range [2-18 GHz] with a home-made near-field microwave microscope. The instrument is built on a vector network analyzer, a matching network, and an evanescent microwave probe. The interferometer-…
