Second-harmonic generation from periodic arrays of arbitrary shape plasmonic nanostructures: a surface integral approach

Olivier Martin, Jérémy Butet, Benjamin Gallinet, Krishnan Thyagarajan

A surface integral formulation for the second-harmonic generation (SHG) from periodic metallic-dielectric nano-structures is described. This method requires the discretization of the scatterers' surface in the unit cell only. All the physical quantities in ...

A model for self-consistent simulation of ICRH suitable for integrating modelling

Laurent Villard

A self-consistent modelling of ion cyclotron resonance heating (ICRH) is reviewed with the aim of obtaining a fast robust scheme suitable for routine simulation for transport codes and data analysis. Due to the complexity of calculating the wave field and ...

Guessing the fingerings from musical recordings

Paolo Prandoni, Arnaud Latty, Frederike Dümbgen

Synopsis: This project is about using musical recordings of string instruments to determine on which strings notes have been played. It includes the study of the spectral content of the recordings and the development of a robust classifica ...

3rd harmonic ECRH absorption enhancement by 2nd harmonic heating at the same frequency in a tokamak

Stefano Coda, Timothy Goodman, Joan Decker, Silvano Gnesin

The fundamental mechanisms responsible for the interplay and synergy between the absorption dynamics of extraordinary-mode electron cyclotron waves at two different harmonic resonances (the 2nd and 3rd) are investigated in the TCV tokamak. An enhanced 3rd ...

Enhanced second-harmonic generation from double resonant plasmonic antennae

Olivier Martin, Andrea Lovera, Krishnan Thyagarajan, Simon Rivier

We present a novel plasmonic antenna geometry - the double resonant antenna (DRA) - that is optimized for second-harmonic generation (SHG). This antenna is based on two gaps coupled to each other so that a resonance at the fundamental and at the doubled fr ...

Geometries and vibrational frequencies of small radicals: Performance of Coupled Cluster and more approximate methods

Jeremy Samuel Arey, Peter Rudolf Tentscher

We generated a new set of reference geometries of small radicals using experimental equilibrium structures, as well as a benchmark-quality coupled cluster additivity scheme including up to quadruples excitations (CCSDTQ). Using these geometries and a set o ...

Accurate Voltage Ripple Estimation and Decoupled Current Control for Modular Multilevel Converters

Alfred Rufer, Michail Vasiladiotis, Nicolas Cherix

The analytical solution for the sub-module voltage ripple equations of a Modular Multilevel Converter (MMC) is derived, based on the knowledge of the external voltage/current magnitudes and enhancing a concept previously presented in literature. In order t ...

Termination of atrial fibrillation by catheter ablation can be successfully predicted from baseline ECG

Jean-Marc Vesin, Andréa Buttu, Jérôme Sébastien Van Zaen, Etienne Pruvot

Several organization indices have been used to predict the outcome of stepwise catheter ablation (step-CA) in long-standing persistent atrial fibrillation (LS-pAF), however with limited success. Our study aims at developing innovative indices from baseline ...

Lateral shearing interferometry of high-harmonic wavefronts

Christopher Alexander Arrell

We present a technique for frequency-resolved wavefront characterization of high harmonics based on lateral shearing interferometry. Tilted replicas of the driving laser pulse are produced by a Mach-Zehnder interferometer, producing separate focii in the t ...

ECG periodic components as a promising tool for complexity assessment during stepwise ablation of atrial fibrillation

Jean-Marc Vesin, Andréa Buttu, Jérôme Sébastien Van Zaen, Etienne Pruvot

Introduction: Stepwise radiofrequency catheter ablation (step-CA) has become a treatment of choice for the restoration of sinus rhythm (SR) in patients (pts) with long-standing persistent atrial fibrillation (pers-AF). Its success rate appears limited as t ...
