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…

On wafer millimetre wave power detection using a PN junction diode in BiCMOS 55 nm for in-situ large signal characterization

Joao Carlos Azevedo Goncalves, Issa Alaji, Daniel Gloria, Vincent Gidel, Frederic Gianesello, Sylvie Lepilliet, Guillaume Ducournau, Francois Danneville, Christophe Gaquière

This paper describes millimetre wave (mmW) on-wafer power detection using dedicated high frequency diode junction with a cut-off frequency (fc) of 400 GHz, integrated in SiGe BiCMOS 55 nm technology from STMicroelectronics. This extraction was performed in order to develop fully integrated power…

Accuracy of parameter identification using the dispersion of surface waves and the role of data quality for inhomogeneous concrete

Radoslaw Drelich, Mariusz Kaczmarek, Bogdan Piwakowski

We study the influence of the data quality on the accuracy of parameter identification for inhomogeneous concrete. The surface of the concrete may differ as a result of either intentional action (decoration or repair) or the interaction of initially homogeneous concrete with the environment. Non-…

Modeling of a Circular Ring MEMS Resonator with Voltage Excitation by Means of an Orthogonal Polynomial Method

Ismail Naciri, Abdessamad Rguiti, Lahoucine Elmaimouni, Jean-Etienne Lefebvre, Faniry Emilson Ratolojanahary, Tadeusz Gryba

The three-dimensional vibrational behavior of a piezoelectric circular ring made of a 6 mm hexagonal material is studied using Legendre polynomial method. The method is simple to implement and based on expanding the electrical potential and the mechanical displacement components in a double series…

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…

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…
