Dispersionless optical activity in metamaterials

Hannam, Kirsty; Powell, David A.; Shadrivov, Ilya V.; Kivshar, Yuri S.

Description

We introduce a chiral metamaterial with strong, non-resonant optical activity, and very low polarization ellipticity. We achieve this by combining a meta-atom and its complementary structure into a meta-molecule, resulting in the coupling of magnetic and electric dipole responses. In contrast to either a pair of crosses, or complementary crosses, this structure has low dispersion in the optical activity at the transmission resonance. We also study the excitation mechanism in this...[Show more]
