Epsilon-near-zero behavior from plasmonic Dirac point: Theory and realization using two-dimensional materials

Mattheakis, Marios; Valagiannopoulos, Constantinos; Kaxiras, Efthimios (Physical Review B. American Physical Society, 2016)

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 (ENZ) behavior. This theoretical result ...
Judicious distribution of laser emitters to shape the desired far-field patterns

Valagiannopoulos, Constantinos; Kovanis, Vassilios (PHYSICAL REVIEW A, 2017-06-06)

In this paper, motivated by such trends in coupled optical oscillators and applied mathematics methods, we inject an inverse-design approach in the construction of the far field of multiple radiating optical apertures. ...
