Exceptional Cones in 4D Parameter Space
Qiang Wang, Kun Ding, Hui Liu +2
The notion of synthetic dimensions has expanded the realm of topological physics to four dimensional (4D) space lately. In this work, non-Hermiticity is used as a synthetic paramet…
Realization of Photonic Charge-2 Dirac Point by Engineering Super-modes in Topological Superlattices
Mengying Hu, Kun Ding, Tong Qiao +4
Quite recently a novel variety of unconventional fourfold linear band degeneracy points has been discovered in certain condensed-matter systems. Contrary to the standard 3-D Dirac…
Controlling Thermal Emission by Parity-symmetric Fano Resonance of Optical Absorbers in Metasurfaces
Xia Zhang, Zhen-guo Zhang, Qiang Wang +2
In this study, we designed a metasurface based on Al/SiN/Al nano-sandwich optical absorbers. Parity-symmetric dark magnetic resonance modes, anti-symmetric bright magnetic resonanc…
Transformation optics based on metasurfaces
Chong Sheng, Hui Liu, Shining Zhu
Recently, new artificial material has been proposed to control an electromagnetic wave-metasurface, a two-dimensional metamaterial. Compared with a three-dimensional bulky metamate…
