Metamaterial Perfect Absorber Analyzed by a Meta-cavity Model Consisting of Multilayer Metasurfaces
Khagendra Bhattarai, Sinhara Silva, Kun Song +4
We demonstrate that the metamaterial perfect absorber behaves as a meta-cavity bounded between a resonant metasurface and a metallic thin-film reflector. The perfect absorption is…

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…
