Low-loss Broadband Negative Refractive Index due to Nonresonant 2D Helical Chiral Metamaterial
Kun Song, Min Wang, Zhaoxian Su +6
We demonstrated a 2D helical chiral metamaterial that exhibits broadband strong optical activity resulting nonresonant Drude-like response. The strong chirality leads to broadband…

Broadband angle- and permittivity-insensitive nondispersive optical activity based on chiral metamaterials
Kun Song, Min Wang, Zhaoxian Su +6
Because of the strong inherent resonances, the giant optical activity obtained via chiral metamaterials generally suffers from high dispersion, which has been a big stumbling block…

Broadband dispersionless polarization rotation with composite chiral metamaterials
Kun Song, Changlin Ding, Yahong Liu +2
We propose a planar composite chiral metamaterial (CCMM) by symmetrically inserting a metallic mesh between two layers of conjugated gammadion resonators. As the elaborate CCMM ope…
