Xavier ROMAIN : "Study of the polarization of light through a stack of metallic metamaterials"

Thesis work : "Study of the polarization of light through a stack of metallic metamaterials"

This PhD thesis deals with the theoretical study of stacked metallic metamaterials. Such structures are currently investigated to extend the functionalities offered by single metallic metamaterials. We especially focus on the specific polarization properties of the stacked metallic metamaterials.

We first present the type of metamaterial that we consider, and we describe the modal method that is used to model its electromagnetic properties. We outline the linear polarization properties characterizing the metamaterial thanks to an Extended Jones Formalism (EJF) recentlydeveloped by our team.

In combination with the EJF, we apply the Smatrix algorithm to the study of a stack of two metallic metamaterials in a polarizer-analyzer configuration. We derive an analytical expression for the transmission response of the stacked structure: the Extended Malus’ Law. Mainly, it highlights the Fabry-Perot-like resonances located between the metamaterials.
