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…

Anomalous refraction based on acoustic metasurfaces with membranes
Shilong Zhai, Changlin Ding, Huaijun Chen +3
The investigation of metasurface, which is of great current interest, has opened up new degrees of freedom to research metamaterials. In this paper, we propose an ultrathin acousti…
