Experimental investigation of the propagation properties of Bloch surface waves on dielectric multilayer platform

Hans Peter Herzig, Elsie Barakat, Richa Dubey

Background: The periodic dielectric multilayers sustaining Bloch surface waves have been proposed as a platformfor the sensing applications and the two dimensional integrated optics. In this paper, we present the experimental and theoretical investigation ...

The Velocity of the Propagating Wave for General Coupled Scalar Systems

Nicolas Macris, Rafah El-Khatib

We consider spatially coupled systems governed by a set of scalar density evolution equations. Such equations track the behavior of message-passing algorithms used, for example, in coding, sparse sensing, or constraint-satisfaction problems. Assuming that ...

Photoacoustics with coherent light

Emmanuel André Henri Bossy

Since its introduction in the mid-nineties, photoacoustic imaging of biological tissue has been one of the fastest growing biomedical imaging modality, and its basic principles are now considered as well established. In particular, light propagation in pho ...

Silicon micromachined ultrasonic scalpel for the dissection and coagulation of tissue

Nico de Rooij, Danick Briand, Pierre-André Farine, Alexis Boegli, Robert Andrew Lockhart, Christian Robert, Patrick Stadelmann

This work presents a planar, longitudinal mode ultrasonic scalpel microfabricated from monocrystalline silicon wafers. Silicon was selected as the material for the ultrasonic horn due to its high speed of sound and thermal conductivity as well as its low d ...

Detection and reconstruction of large-scale coherent flow structures in gravel-bed rivers

Ulrich Lemmin, Mário Jorge Rodrigues Pereira Da Franca

Large-scale flow structures (LSFS) in the streamwise direction are important features of gravel-bed river flows, because they may contribute to sediment transport and gas exchange. In the present study, these structures are detected using Huang's empirical ...

Existence and Uniqueness Theorems in Two-Dimensional Nematodynamics. Finite Speed of Propagation

Tudor Ratiu

The paper is devoted to the two-dimensional Ericksen-Leslie system describing the nematodinamics of liquid crystals. The moment of inertia of molecules is supposed to be strictly positive. The existence of the solution was proved in the case of periodic do ...

Keynote lecture - Potential, limits and perspectives of physical and numerical modelling

Giovanni De Cesare

In the 19th Century, hydraulic engineering was typically addressed in two parallel approaches. On one hand, classical theoretical fluid mechanics with the use of analytical approaches to study various flow occurrences. Due to the difficulty and complexity ...

A study of frictional contact in dynamic fracture along bimaterial interfaces

Jean-François Molinari, Fabian Barras, David Simon Kammer

We investigate numerically the dynamic inplane propagation of a centered crack along bimaterial interfaces using a spectral formulation of the elastodynamic boundary integral equations. Particular attention is given to the effect of contact zones at the su ...

Evolution of heterogeneous stress distributions created by slip precursors in numerical simulations of frictional interfaces

Jean-François Molinari, Mathilde Edmée Lucette Radiguet de la Bastaie, David Simon Kammer

Understanding how a frictional interface fails, and how past ruptures will affect the propagation of the following ruptures is fundamental to a better comprehension of earthquake behavior. In that sense, numerical simulations provide a useful tool to study ...

A further study on seismic response of a set of parallel rock fractures filled with viscoelastic materials

Jian Zhao, Wei Wu, Jianbo Zhu

The purpose of this study is to further investigate the seismic response of a set of parallel rock fractures filled with viscoelastic materials, following the work by Zhu et al. Dry quartz sands are used to represent the viscoelastic materials. The split H ...
