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…

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…
