Acoustic noise levels and field distribution in 7 T MRI scanners

Louena Shtrepi, Vinicius Poggetto, Clement Durochat, Marc Dubois, David Bendahan, Fabio Nistri, Marco Miniaci, Nicola Maria Pugno, Federico Bosia

Acoustic noise production during Magnetic Resonance Imaging is an important source of patient discomfort and leads to verbal communication problems, difficulties in sedation, and hearing impairment. To address these issues, in this paper we present a systematic characterization of the acoustic…

Experimental evidence of nonreciprocal propagation in space-time modulated piezoelectric phononic crystals

S. Tessier Brothelande, C. Croënne, F. Allein, Jerome O. Vasseur, M. Amberg, Frédéric Giraud, Bertrand Dubus

A nonreciprocal system composed of a one-dimensional piezoelectric phononic crystal whose periodic electrical conditions are modulated in time is presented. One-way longitudinal wave propagation is studied experimentally and compared to finite element temporal simulations. The modulation is…

Process optimization of Fully Vertical GaN-on-Silicon PIN diodes

Idriss Abid, Youssef Hamdaoui, Sondre Michler, Katir Ziouche, F Medjdoub

Lateral GaN-on-silicon power transistors are now qualified up to 650 V voltage operation [1]. On the other hand, the development of cost-effective GaN-based vertical devices grown on large diameter silicon substrate combines the advantages of potentially higher voltage operation with avalanche…

15. GaN-Based Lateral and Vertical Devices

Matteo Meneghini, Srabanti Chowdhury, Joff Derluyn, Farid Medjdoub, Dong Ji, Jaeyi Chun, Riad Kabouche, Carlo de Santi, Enrico Zanoni, Gaudenzio Meneghesso

In the last decade, GaN has emerged as an excellent material for application in power electronics. The wide energy gap of gallium nitride (3.4 eV) enables high-temperature operation, while the large breakdown field (3.3 MV/cm, 11 times higher than silicon) allows to reach kV-range operation while…
