Title:  Optical Phenomena and Resonances in the Homogenization of Layered Heterostructures

Abstract: An important class of metamaterials consists of plasmonic crystals that are made of stacked metallic or semi-metallic 2D material structures arranged periodically with subwavelength spacing and embedded in a dielectric host. They offer a level of control of the path and dispersion of light that is of fundamental interest and leads to exciting new optical devices and applications. A particularly important building block in creating such a plasmonic crystal are atomically thick 2D metallic sheets, for example graphene or black phosphorus.

In this talk we present analytical and computational approaches to simulate resonant effects of surface plasmon polaritons (SPPs) on 2D material interfaces and layered heterostructures. The computational approach is based on a homogenization theory for layered heterostructures and an adaptive finite-element simulation framework. We present a spectral analysis of the cell problem that quantitatively describes resonances in the effective material parameters of plasmonic crystals.
