Development of PZT-based 18 MHz 2D pMUT array with PDMS waveguide

Xu-Bo Wang, Le-Ming He, Wen-Juan Liu, Shu-Ren Song, Wei-Jiang Xu, Qian Cheng, Antoine Riaud, Jun-Yan Ren, Jia Zhou

For high-resolution ultrasonic imaging, an 18 MHz lead zirconate titanate (PZT) based two-dimensional (2D) piezoelectric micromachined ultrasonic transducers (pMUTs) array with polydimethylsiloxane (PDMS) waveguide are developed. The array is composed of 8 x 16 elements with a pitch of 75 mu m and...

Tunable frequency band structure in photo-responsive elastic metamaterials

A.S. S Gliozzi, M. Miniaci, A. Chiappone, A. Bergamini, F. Bosia, E. Descrovil, E Descrovi

An important issue in the field of elastic metamaterials is that their dynamic properties, such as the band gap frequencies, are typically fixed once the structure has been designed and fabricated. To overcome this limitation, many efforts have been made to conceive materials with adaptive elastic...

Electrothermal modeling of GaN power transistor for high frequency power converter design

Loris Pace, Florian Chevalier, Arnaud Videt, N. Defrance, Nadir Idir, Jean-Claude de Jaeger

This work proposes the electrothermal modeling of a packaged GaN power transistor in order to evaluate by simulation its performances in a 200 W - 1 MHz DC/DC converter. The complete electrical modeling of the high frequency converter using EM-circuit co-simulations is presented. After validation...

Illumination-robust face recognition based on deep convolutional neural networks architectures

Ridha Ilyas Bendjillali, Mohammed Beladgham, Khaled Merit, Abdelmalik Taleb-Ahmed

In the last decade, facial recognition techniques are considered the most important fields of research in biometric technology. In this research paper, we present a Face Recognition (FR) system divided into three steps: The Viola-Jones face detection algorithm, facial image enhancement using...
