SUMMARY:FAU-CAAAvH Seminar: Stability and asymptotic properties of a linearized hydrodynamic medium model for dispersive media in nanophotonics
DESCRIPTION:Speaker: Prof. Dr. Serge Nicaise\nAffiliation: Université Polytechnique Hauts-de-France, France\nAbstract. In this talk, we will present a linearized hydrodynamical model describing the response of nanometric dispersive metallic materials illuminated by optical light waves, a situation occurring in nanoplasmonics. The model corresponds to the coupling between the Maxwell system and a PDE describing the evolution of the polarization current of the electrons in the metal. First by using semigroup theory its well posedness will be shown. Then using a frequency approach, a polynomial (and optimal) stability result will be presented. We will also investigate the numerical stability for a discontinuous Galerkin type approximation and several explicit time integration schemes. Numerical tests that confirm our theoretical prediction will be given.\nThis is a join work with Claire Scheid (Université Côte d’Azur, France)\nMore about this seminar (FAU CAA-AvH website)\n
