Prof. Charles Stuart (EPF Lausanne): Modeling axi-symmetric traveling waves in a dielectric with nonlinear refractive index
We consider the propagation of monochromatic travelling waves through a dielectric medium with a nonlinear refractive index. The medium may be heterogeneous, but it has cylindrical symmetry. We consider all travelling waves having this cylindrical symmetry. We show that, for such solutions, Maxwell's equations reduce to a system of six coupled second order ordinary differential equations. The usual equations for TE and TM modes appear as special cases of this system.

Prof. Dr. Wolfgang Reichel

A-priori bounds for discrete and continuous elliptic boundary value problems
Zusammenfassung: On a bounded domain consider nonlinear elliptic boundary value problems of the form \Delta u = f(x,u) together with its finite difference discretization \Delta_h u = f(x,u). If positive weak solutions of the continuous problem (with zero Dirichlet boundary conditions) satisfy apriori bounds, is the same true for the discretized problem? In this talk I will address some recent developments concerning this question.

Prof. Dr. Roland Schnaubelt

Wellposedness of Maxwell's equations with boundary control and observation
Zusammenfassung: We consider linear homogeneous Maxwell's equations with time depending scalar electric permittivity and magnetic permeability subject to a certain class of boundary control and observation. The wellposedness of this control system is established by treating it as a multiplicative time varying perturbation of a time invariant control problem.

Titel: A posteriori error estimation and h-adaptive finite element methods for the time harmonic Maxwell equations
Abstract: An h-adaptive finite element approximation of the time harmonic Maxwell equations is presented. As a main ingredient of the adaptation algorithm a local a posteriori error estimate is analyzed. The performance of the error estimator and the FE solver are tested on a series of non-trivial examples.
