Degradation of InGaN-based MQW solar cells under 405 nm laser excitation

Carlo de Santi, Matteo Meneghini, Alessandro Caria, Ezgi Dogmus, Malek Zegaoui, F Medjdoub, Enrico Zanoni, Gaudenzio Meneghesso

Within this paper we analyze the reliability of 25 × multi quantum well InGaN-based devices, designed to be used as high power photodetectors or in multi-junction solar cells. Under stress with monochromatic excitation at 405 nm by means of a laser diode, we detect degradation at optical power…

Free-Space Characterization of Magneto-Optical Hexaferrites in the Submillimeter-Wave Range

Tomas Horak, Guillaume Ducournau, Martin Micica, Kamil Postava, Jamal Ben Youssef, Jean-Francois Lampin, Mathias Vanwolleghem

We present the quasi-optical free-space characterization of magneto-optical hexagonal ferrites-crystalline BaFe 12 O 19 and both ceramic and crystalline SrFe 12 O 19 -in the range between 325 and 500 GHz using a vector network analyzer. This method provides us the full complex spectrum of the 2 × 2…

Fast time-domain laser Doppler vibrometry characterization of surface acoustic waves devices

Nikolay Smagin, Lyes Djoumi, Etienne Herth, Meddy Vanotti, Dame Fall, Virginie Patissier, Marc Duquennoy, Mohammadi Ouaftouh

This paper explores experiments and an in-depth analysis of surface acoustic waves (SAW) imaging using scanning laser Doppler vibrometry. Optical measurements allow visualization of wave propagation and resonance patterns in SAW devices as well as the detection of loss sources and undesired…

Heart rate estimation using facial video: A review

M.A. Hassan, A.S. Malik, D. Fofi, N. Saad, B. Karasfi, Y.S. Ali, F. Meriaudeau

Photoplethysmography and Ballistocardiography are two concepts that are used to measure heart rate from human, by using facial videos. Heart rate estimation is essential to determine the physiological and pathological state of a person. This paper presents a critical review of digital camera based…

Linear Finite-Difference Bond Graph Model of an Ionic Polymer Actuator

Mohamed Bentefrit, Sébastien Grondel, Caroline Soyer, Adelyne Fannir, Eric Cattan, John D.W. Madden, Giao T.M. Nguyen, Cedric Plesse, Frederic Vidal

With the recent growing interest for soft actuation, many new types of ionic polymers working in air have been developed. Due to the interrelated mechanical, electrical, and chemical properties which greatly influence the characteristics of such actuators, their behavior is complex and difficult to…

Dielectric characterization based on a printable resonant stub in air and a liquid environment

Kamel Guerchouche, Etienne Herth, Laurie E. Calvet, Nathalie Roland, Christophe Loyez

This paper develops a new approach for in situ characterization of specific dielectric-based products that are located in complex geometric containers. The method uses a resonant T-topology of microstrip lines realized on a flexible substrate. This narrowband interferometric technique consists of…
