Abstract

We demonstrate numerically and experimentally that uniaxial chiral metamaterial creates giant optical activity and circular dichroism due to the large chirality. Also, transmission and reflection coefficients, circular dichroism and chirality values are separately examined and evaluated. The presented chiral designs are combined of the discontinuous bilayer cross-wire patterned on opposite sides. It offers a much simpler geometry and more efficient results. The experimental results are in good agreement with the numerical simulations.
