Abstract:
Patterning of thin metal films on the sub-wavelength scale can yield a range of functionalities invaluable for nanophotonic application.
We provide an overview of advances in developing microwave, terahertz and photonics metamaterials consisting of three- and two- dimensional chiral meta-molecules and show how molecular chirality leads to negative index of refraction and asymmetric transmission of light. We also describe the recently introduced concept of extrinsic chirality arising from the mutual orientation of non-chiral planar metamaterial structures and the incident electromagnetic wave.
