Non-Hermitian chiral degeneracy of gated graphene metasurfaces
Soojeong Baek, Sang Hyun Park, Donghak Oh +9
Non-Hermitian degeneracies, also known as exceptional points (EPs), have been the focus of much attention due to their singular eigenvalue surface structure. Nevertheless, as perta…
Real-space imaging of acoustic plasmons in large-area CVD graphene
Sergey G. Menabde, In-Ho Lee, Sanghyub Lee +8
An acoustic plasmonic mode in a graphene-dielectric-metal heterostructure has recently been spotlighted as a superior platform for strong light-matter interaction. It originates fr…
Observation of an exceptional point in a non-Hermitian metasurface
Sang Hyun Park, Sung-Gyu Lee, Taewoo Ha +6
Exceptional points, also known as non-Hermitian degeneracies, have been observed in parity-time symmetric metasurfaces as the parity-time symmetry breaking point. However, the pari…
Extremely broadband topological surface states in a photonic topological metamaterials
Minkyung Kim, Dasol Lee, Wenlong Gao +4
Metamaterials, artificially engineered materials consisting of subwavelength unit cell, have shown potentials in light manipulation with their extraordinary optical properties. Esp…
Pancharatnam-Berry phase induced spin-selective transmission in herringbone dielectric metamaterials
Mitchell Kenney, Shaoxian Li, Xueqian Zhang +9
Manipulating the polarisation of light is crucial for sensing and imaging applications. One such aspect in particular is selective transmission of one circular polarisation (spin)…
