Job Description
Thesis Subject
Photonic crystals are manufactured optical nanostructures (designed to control wave propagation) characterized by a periodic refractive index. Their modeling is based on the spectral analysis of the underlying wave operator. In these media, symmetries play a fundamental role. Thus, much like graphene in solid-state physics, materials with honeycomb symmetry exhibit exceptional properties: for example, introducing a linear defect into such media allows for the creation of extremely stable guided modes, which are particularly interesting from an applied perspective. This is referred to as topological stability. The objective of this project is to study these media in electromagnetics and acoustics, based on asymptotic models. We will examine the stability of spectral properties with respect to symmetries as well as the behavior of these media in the time domain.
