Six states of splitting waves are observed when an electromagnetic wave propagates
through wedge-shaped chiral metamaterials. The chirality and electromagnetic parameters,
as well as the material parameter factor, are the main influences controlling the refractive
indices of the material and the rotations of the out-going waves. The incidence angle or the
angle of the wedge has a major impact on selecting the out-going waves and the occurrence
of an evanescent wave. This new study discloses some of the less known aspects of chiral
metamaterial design leading to a broader range of applications in optical devices.
