Numerical resolution of some Helmholtz-type problems with impedance boundary condition or PML, Résolution numérique de quelques problèmes du type Helmholtz avec conditions au bord d'impédance ou des couches absorbantes (PML)

Jérôme Tomezyk

In this thesis, we propose wavenumber explicit convergence analyses of some finite element methods for time-harmonic Maxwell's equations with impedance boundary condition and for the Helmholtz equation with Perfectly Matched Layer (PML). We first study the regularized formulation of time-..., Dans cette thèse, nous étudions la convergence de méthode de type éléments finis pour les équations de Maxwell en régime harmonique avec condition au bord d'impédance et l'équation de Helmholtz avec une couche parfaitement absorbante(PML). On étudie en premier, la formulation régularisée...

Local Electrical Characterization of PVDF Textile Filament

Anthony Ferri, François Rault, Antonio da Costa, Cédric Cochrane, Matthieu Boudriaux, Guillaume Lemort, Christine Campagne, Eric Devaux, Christian Courtois, Rachel Desfeux

The piezoelectric behavior of poly(vinylidene fluoride), PVDF, has been known for several decades and is clearly related to its crystalline phases. Many works made on films or fibers have focused on the characterization of the phase transitions during various PVDF processing and on its...
