A quasi-static two-dimensional induction heating problem. I: Modelling and analysis

We consider a nonlinear elliptic-parabolic system modelling induction heating processes when a sinusoidal electromagnetic field is applied at the boundary of the inductor. The magnetic field satisfies an elliptic equation whereas the temperature equation i ...

Extension of the generalized multipole technique to anisotropic medias

Olivier Martin

This paper presents an extension of the generalized multipole technique (GMT) for 2D anisotropic scatterers. New expansions similar to the Bessel multipole expansion are derived for arbitrary anisotropic media. Numerical simulations prove the accuracy and ...

Modélisation des transformations de phase à l'état solide dans les aciers et application au traitement thermique par induction

Alain Jacot

In the first part of this work a comprehensive model of the continuous hardening of 3D-axisymmetric steel components by induction heating has been developed. In the model, the Maxwell and heat flow equations are solved using a mixed numerical formulation : ...

Microcavity polaritons: Homogeneous and inhomogeneous broadening in the strong coupling regime

Vincenzo Savona

The exciton-polariton states of quantum wells embedded in planar semiconductor microcavities are usually described by assuming in-plane wave vector conservation. In this work we consider the two main k(parallel to)-scattering mechanisms, namely the polarit ...

Modelling of electromagnetic heating, cooling and phase transformations during surface hardening of steels

Michel Rappaz, Jacques Rappaz, Daniele Mari, Alain Jacot

A comprehensive micro-macroscopic model of the continuous hardening of 3d-axisymmetric steel components by induction heating has been developed. At the macroscopic scale, the Maxwell and heat flow equations are solved using a mixed numerical formulation : ...

Generation Of Optical Standing Waves Around Mesoscopic Surface-Structures - Scattering And Light Confinement

Olivier Martin

Optical scanning probe devices offer an extremely efficient way of collecting local information on the complex structure of optical electromagnetic fields lying near a surface. This paper discusses recent theoretical efforts to develop an efficient method ...

Generalized Energy-Balance and Reciprocity Relations for Thin-Film Optics

Marc-André Dupertuis

Energy balance and reciprocity relations are studied for harmonic inhomogeneous plane waves that are incident upon a stack of continuous absorbing dielectric media that are macroscopically characterized by their electric and magnetic permittivities and the ...
