Comparison of gold- and graphene-based resonant nano-structures for terahertz metamaterials and an ultra-thin graphene-based modulator
Nian-Hai Shen, Philippe Tassin, Thomas Koschny +1
Graphene exhibits unique material properties and in electromagnetic wave technology, it raises the prospect of devices miniaturized down to the atomic length scale. Here we study s…
One- and two-dimensional photo-imprinted diffraction gratings for manipulating terahertz waves
Ioannis Chatzakis, Philippe Tassin, Liang Luo +5
Emerging technology based on artificial materials containing metallic structures has raised the prospect for unprecedented control of terahertz waves through components like filter…
Robust wedge demonstration to optical negative index metamaterials
Nian-Hai Shen, Thomas Koschny, Maria Kafesaki +1
A robust wedge setup is proposed to unambiguously demonstrate negative refraction for negative index metamaterials. We applied our setup to several optical metamaterials from the l…
