Two dimensional modeling of elastic wave propagation in solids containing cracks with rough surfaces and friction – Part I: Theoretical background

Vladislav Aleshin, Steven Delrue, Andrey Trifonov, Olivier Bou Matar, Koen van den Abeele

Abstract Our study aims at the creation of a numerical toolbox that describes wave propagation in samples containing internal contacts (e.g. cracks, delaminations, debondings, imperfect intergranular joints) of known geometry with postulated contact interaction laws including friction. The code...

Scanning microwave microscopy of vital mitochondria in respiration buffer

Jinfeng Li, Zahra Nemati, Kamel Haddadi, Douglas C. Wallace, Peter J. Burke

We demonstrate imaging using scanning microwave microscopy (SMM) of vital mitochondria in respiration buffer. The mitochondria are isolated from cultured HeLa cells and tethered to a solid graphene support. The mitochondria are kept vital (alive) using a respiration buffer, which provides nutrients...

Microscale ultrahigh-frequency resonant wireless powering for capacitive and resistive MEMS actuators

Yoshio Mita, Naoyuki Sakamoto, Naoto Usami, Antoine Frappé, Akio Higo, Bruno Stefanelli, Hidehisa Shiomi, Julien Bourgeois, Andreas Kaiser

This paper presents a versatile chip-level wireless driving method for microelectromechanical system (MEMS) actuators. A MEMS actuator is integrated as an electrical component of a coupled LCR resonant circuit, and it rectifies the energy sent through an ultrahigh-frequency (UHF) radio frequency (...

Gallium nitride MEMS resonators: how residual stress impacts design and performances

Christophe Morelle, Didier Theron, Joff Derluyn, Stefan Degroote, Marianne Germain, Victor Zhang, Lionel Buchaillot, Bertrand Grimbert, Pascal Tilmant, Francois Vaurette, Isabelle Roch-Jeune, Virginie Brandli, Vanessa Avramovic, Etienne Okada, Marc Faucher

Starting from Gallium Nitride epitaxially grown on silicon, pre-stressed micro-resonators with integrated piezoelectric transducers have been designed, fabricated, and characterized. In clamped-clamped beams, it is well known that tensile stress can be used to increase the resonant frequency. Here...

Strain-Reduction Induced Rise in Channel Temperature at Ohmic Contacts of GaN HEMTs

Steven Duffy, Brahim Benbakhti, Karol Kalna, Mohammed Boucherta, Wei Zhang, Nour Eddine Bourzgui, Ali Soltani

ABSTRACT Operating temperature distributions in AlGaN/GaN gateless and gated devices are characterized and analyzed using the InfraScope temperature mapping system. For the first time, a substantial rise of channel temperature at the inner ends of ohmic contacts has been observed. Synchrotron...

Perspective: organic electronic materials and devices for neuromorphic engineering

Sébastien Pecqueur, Dominique Vuillaume, F. Alibart

Neuromorphic computing and engineering has been the focus of intense research efforts that have been intensified recently by the mutation of Information and Communication Technologies (ICT). In fact, new computing solutions and new hardware platforms are expected to emerge to answer to the new...

An extension of the RiMAX multipath estimation algorithm for ultra-wideband channel modeling

Brecht Hanssens, Emmeric Tanghe, Davy Gaillot, M. Lienard, Claude Oestges, David Plets, Luc Martens, Wout Joseph

This work presents an extension of the high-resolution RiMAX multipath estimation algorithm, enabling the analysis of frequency-dependent propagation parameters for ultra-wideband (UWB) channel modeling. Since RiMAX is a narrowband algorithm, it does not account for the frequency-dependency of the...

A dual-bandwearable exposure meter for personal RF exposure assessment in indoor environments: on-body calibration in a reverberation chamber

Reza Aminzadeh, Arno Thielens, Davy Gaillot, M. Lienard, Sam Agneessens, Patrick van Torre, Matthias van den Bossche, Hendrik Rogier, Martin Roosli, Luc Martens, Wout Joseph

For the first time, a dual band wearable personal distributed exposure meter (DPDE) is designed. The DPDE is calibrated on-body in a reverberation chamber. The meter consists of four nodes including textile antennas operating at 2443 MHz (WiFi 2 GHz) and 2595 MHz (LTE 2600 MHz). The location of the...
