Resonant and scattering exceptional points in non-Hermitian metasurfaces

Abstract Exceptional points (EPs), as unique singularities in non-Hermitian systems, can trigger distinctive effects in open quantum systems. This review proposes a systematic framework to analyze EP characteristics in non-Hermitian metasurfaces. Starting from the foundational theory of parity-time...
