Structural health monitoring of hollow cylinder using cross-correlation of ambient noise field

Sonia Djili, Emmanuel Moulin, Jamal Assaad, Malika Toubal, Farouk Benmeddour

This work is devoted to the Structural Health Monitoring (SHM) of hollow cylinders. To this end, the generated noise by fluid flow (liquid or gas) is exploited. First, a one-dimensional theoretical model is developed. This is based on the cross-correlation function. It is shown that the latter…

Conversion between surface acoustic waves and guided modes of a quasi-periodic structured nanobeam

Alexander V Korovin, Yan Pennec, Matteo Stocchi, Davide Mencarelli, Luca Pierantoni, Tapani Makkonen, Jouni Ahopelto, Bahram Djafari-Rouhani

The generation of acoustic waves in structured nanobeams containing optomechanic cavities is a topic of current interest. In this paper, we theoretically study the efficient conversion of surface acoustic waves (SAW) generated on a substrate by an RF electric signal into the acoustic waves of a…

Accuracy of Green's function estimation from correlation of diffuse elastic waves on thin plates

Lynda Chehami, Emmanuel Moulin, Julien de Rosny, Claire Prada

In a reverberant cavity, when a noise field is sufficiently diffuse, the correlation of the signal measured by two sensors provides an estimation of the Green's function (GF) between them. Here, the convergence of this passive estimation in the case of elastic waves on thin plates is studied.…

On evaporation via an inclined rotating circular lift-off shadow or stencil mask

S. Arscott

A mathematical model is developed to calculate the topography of a mesa obtained by evaporation of matter via inclined rotating lift-off shadow masking. Two types of masking are considered: a circular mask and a cylindrical mask-the latter involves sidewall deposition. The model is able to predict…

Design and Implementation of Ternary Logic Integrated Circuits by Using Novel Two-Dimensional Materials

Mingqiang Huang, Xingli Wang, Guangchao Zhao, Philippe Coquet, Bengkang Tay

With the approaching end of Moore’s Law (that the number of transistors in a dense integrated circuit doubles every two years), the logic data density in modern binary digital integrated circuits can hardly be further improved due to the physical limitation. In this aspect, ternary logic (0, 1, 2)…

Transmorphic epitaxial growth of AlN nucleation layers on SiC substrates for high-breakdown thin GaN transistors

Jun Lu, Jr-Tai Chen, Martin Dahlqvist, Riad Kabouche, F Medjdoub, Johanna Rosen, Olof Kordina, Lars Hultman

ABSTRACT Interfaces containing misfit dislocations deteriorate electronic properties of heteroepitaxial wide bandgap III-nitride semiconductors grown on foreign substrates, as a result of lattice and thermal expansion mismatches and incompatible chemical bonding. We report grain-boundary-free AlN…

Towards all-solution-processed top-illuminated flexible organic solar cells using ultrathin Ag-modified graphite-coated poly(ethylene terephthalate) substrates

Shuanglong Wang, Yi Zhao, Hong Lian, Cuiyun Peng, Xuyong Yang, Yulai Gao, Yan Peng, Weixia Lan, Omar Ibrahim Elmi, Didier Stiévenard, Bin Wei, Furong Zhu, Tao Xu

All-solution-processed flexible organic solar cells (FOSCs) with high power conversion efficiency (PCE) are the prerequisite for application in low-cost, large-area, flexible, photovoltaic devices. In this work, high-performance, top-illuminated FOSCs using ultrathin Ag-modified graphite-coated…
