Epsilon-Near-Zero behavior from plasmonic Dirac point: theory and realization using two-dimensional materials

Marios Mattheakis, Constantinos A. Valagiannopoulos, Efthimios Kaxiras

The electromagnetic response of a two-dimensional metal embedded in a periodic array of a dielectric host can give rise to a plasmonic Dirac point that emulates Epsilon-Near-Zero (…
