Description: Optical Phenomena, Resonances, and Homogenization of Layered Heterostructures
Two-dimensional materials with controllable electronic structures have
opened up an unprecedented wealth of optical phenomena that challenge
the classical picture of electromagnetic wave propagation. They are a
promising ingredient in the design of novel optical devices, promising
"subwavelength optics" beyond the diffraction limit.
In this talk we present a homogenization theory of plasmonic crystals
with two-dimensional material inclusions and a spectral analysis
quantitatively describing Lorentz resonances in the effective
permittivity tensor. We conclude by demonstrating how our analytical
findings can serve as an efficient computational tool to describe the
general frequency dependence of periodic optical devices.
