Non-Hermitian chiral degeneracy of gated graphene metasurfaces
We report the precise real-time probing of chiral exceptional points with an electrical and spectral method and the consequences of chiral mode collapsing by an active platform of hybridised non-Hermitian metasurfaces with gated graphene microribbons.
