Conjugated gammadion chiral metamaterial with uniaxial optical activity and negative refractive index
arXiv:1008.5172 · doi:10.1103/PhysRevB.83.035105
Abstract
We demonstrate numerically and experimentally a conjugated gammadion chiral metamaterial that uniaxially exhibits huge optical activity and circular dichroism, and gives a negative refractive index. This chiral design provides smaller unit cell size and larger chirality compared with other published planar designs. Experiments are performed at GHz frequencies (around 6GHz) and in good agreement with the numerical simulations.
