Mathematical Aspects of Wave Propagation in Plasmonic Structures

Organizers of this minisymposium are

Plasmonic structures offer a great potential for exciting applications such as cloaking devices. From a mathematical point of view, the modelling of plasmonic wave propagation raises challenging problems. In particular, it involves dispersive materials which leads to consider eigenvalue problems which are nonlinear with respect to the frequency. The study of plasmonic structures, and more generally of negative metamaterials, also leads to work on transmission problems with sign-changing permittivities and/or permeabilities. This requires to develop new tools because such problems do not enter classical frameworks. The aim of this minisymposium is to discuss different approaches for the analysis and numerical approximation in this context.
