Analysis and design of terahertz antennas based on plasmonic resonant graphene sheets

Juan Ramon Mosig, Julien Perruisseau-Carrier, Michele Tamagnone

Resonant graphene antennas used as true interfaces between terahertz (THz) space waves and a source/detector are presented. It is shown that in addition to the high miniaturization related to the plasmonic nature of the resonance, graphene-based THz antenn ...

Experimental Investigations of Dam Break Flows down an Inclined Channel.

Christophe Ancey, Danilo Marra, Thomas Earl

Dam break floods on steep slopes occur in diverse settings and can encompass natural events such as mudflows and avalanches as well as the failure of manmade dams. Laboratory experiments were undertaken to investigate the dam break flows of pure water down ...

Third-Order Susceptibility of Silicon Crystals Measured with Millimeter-Wave Gyrotron

Jean-Philippe Hogge, Markus Siegrist

We investigate experimental dependence of the third harmonic generation efficiency in the n-type Si crystals on the geometrical dimensions of the sample, polarization and power of the fundamental wave. The efficiency increases monotonically with the rise o ...

Vibrational Relaxation and Intersystem Crossing of Binuclear Metal Complexes in Solution

Majed Chergui, Frank van Mourik, Andrea Cannizzo, Renske Marjan van der Veen

The ultrafast vibrational-electronic relaxation upon excitation into the singlet (1)A(2u) (d sigma*-> p sigma) excited state of the d(8)-d(8) binuclear complex Pt-2(P2O5H2)(4) has been investigated in different solvents by femtosecond polychromatic f ...

Two-dimensional Vlasov simulation of electron plasma wave trapping, wavefront bowing, self-focusing, and sideloss

Stephan Brunner

Two-dimensional Vlasov simulations of nonlinear electron plasma waves are presented, in which the interplay of linear and nonlinear kinetic effects is evident. The plasma wave is created with an external traveling wave potential with a transverse envelope ...

Theoretical and Numerical Analyses of Wave Propagation in Jointed Rock Masses

Jianbo Zhu

Rock masses are distinguished from other engineering materials by the existence of joints. When a wave propagates through a rock mass, it is significantly attenuated due to the reflection and dissipation at joints. Great efforts have been made to study the ...

P-wave Indices to Detect Susceptibility to Atrial Fibrillation

Jean-Marc Vesin, Andréa Buttu

The aim of this work is to present different markers resulting from the analysis of a single ECG lead recorded during sinus rhythm. To this purpose, the ECGs from three populations were compared: healthy subjects, patients subject to paroxysmal AF selected ...

Validation study of the distinct lattice spring model (DLSM) on P-wave propagation across multiple parallel joints

Jian Zhao, Gaofeng Zhao, Jianbo Zhu

A validation study of the distinct lattice spring model (DLSM) for wave propagation problems is performed. DLSM is a microstructure-based numerical model, which is meshless and has advantages in modelling dynamic problems where stress wave propagation is i ...

Beyond the lateral resolution limit by phase imaging

Christian Depeursinge, Muhammed Fatih Toy, Yann Jérôme Michel Pascal Cotte

We present a theory stating how to overcome the classical Rayleigh-resolution limit. It is based upon a new resolution criterion in phase of coherent imaging process and its spatial resolution is thought to be only SNR limited. Recently, the experimental o ...
