Résumé
This talk explores the intriguing realm of scattering resonances within two-dimensional transparent cavities, which arose in the modeling of micro-resonators constructed from dielectric materials (with positive permittivity) or metallic nanoparticles (with negative permittivity). Specifically, our investigation is focused on resonances that closely align with the real axis, characterized by highly oscillatory behavior and localization along the interface separating the cavity from its external environment. Notable exemplars of such resonances include whispering-gallery modes observed in dielectric cavities and surface plasmon waves associated with metallic particles.
