"Multiscale modeling to compute near-fields in plasmonic structures"

Dr. Camille Carvalho
Applied Mathematics
University of California, Merced

Abstract:  Plasmonic structures are made of dielectrics and metals, and at optical frequencies metals exhibit unusual electromagnetic properties like a dielectric permittivity with a negative real part whereas dielectrics have a positive one. This change of sign allows the propagation of electromagnetic surface waves strongly oscillating at the metal-dielectric interface, and hyper-oscillating if the interface presents corners. Standard methods to study surface plasmons excitation do not always take into account the multiple scales inherent in electromagnetic problems which may lead to inaccurate predictions. In this presentation we present some techniques to accurately compute and efficiently take into account the multiple scales of 2D light scattering problems in plasmonic structures 

Biography:  Camille Carvalho received her Ph.D in Applied Mathematics from Ecole Polytechnique (France) with a "magna cum laude" distinction in December 2015. She holds a M.S. degree from the Engineer school ENSTA (France) in simulation and modelization, and a M.S. degree in Applied Mathematics from University Paris 6 with honors. After a post-doc at DEFI (France), she is currently Visiting Assistant Professor at University of California, Merced.
