The motion of long levitating drops in tubes in an anti-Bretherton configuration

Peter Favreau, Alexis Duchesne, Farzam Zoueshtiagh, Michael Baudoin

In his seminal paper, Bretherton [J. Fluid Mech., 10:166 (1961)] studied the motion of long bubbles in capillary tubes, a situation encountered in many two-phase flow systems. Here, we unveil experimentally and numerically the negative configuration, wherein a long liquid drop formed by the rupture…

Design and characterization of power detectors in 55-nm BiCMOS technology for 5G and THz applications, Conception et caractérisation de détecteurs de puissance en technologie BiCMOS 55 nm pour les applications 5G et THz

Issa Alaji

Power detectors are the key blocks to establish the power measurement. Therefore, they are considered among the most important circuits in many microwave and millimeter wave applications (such as communication systems, medical equipments, radar systems, etc.). In this context, this thesis presents…, Les détecteurs de puissance sont les blocs clés pour établir la mesure de puissance. Par conséquent, ils sont considérés parmi les circuits les plus importants dans de nombreuses applications micro-ondes et ondes millimétriques (telles que les systèmes de télécommunication, les équipements médicaux…

Graphene-based one-dimensional terahertz phononic crystal: band structures and surface modes

Ilyasse Quotane, El Houssaine El Boudouti, Bahram Djafari-Rouhani

In this paper, we provide a theoretical and numerical study of the acoustic properties of infinite and semi-infinite superlattices made out of graphene-semiconductor bilayers. In addition to the band structure, we emphasize the existence and behavior of localized and resonant acoustic modes…

A computationally efficient nonlinear dynamic model for cMUT based on COMSOL and MATLAB/Simulink

Yan Wang, Le-Ming He, Ziwei Li, Wei-Jiang Xu, Junyan Ren

Using the plate capacitance model, capacitive micromachined ultrasound transducers (cMUT) cells can be simulated. We present a hybrid model that predicts the dynamic behavior of a cMUT cell with uneven membrane and partial coverage electrode. COMSOL Multiphysics was used to calculate the stationary…

Excitation Intensity and Temperature-Dependent Performance of InGaN/GaN Multiple Quantum Wells Photodetectors

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

In this article, we investigate the behavior of InGaN-GaN Multiple Quantum Well (MQW) photodetectors under different excitation density (616 µW/cm 2 to 7.02 W/cm 2) and temperature conditions (from 25 • C to 65 • C), relating the experimental results to carrier recombination/escape dynamics. We…
