Nonlinear dielectric geometric-phase metasurface with simultaneous structure and lattice symmetry design
Bingyi Liu, René Geromel, Zhaoxian Su +5
In this work, we utilize thin dielectric meta-atoms placed on a silver substrate to efficiently enhance and manipulate the third harmonic generation. We theoretically and experimen…

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…
