摘要

Abstract

Exceptional points (EPs)

singularities of non-Hermitian systems

often exhibit exotic behaviors by engineering the balance between the system gain and loss. Now

EPs have been demonstrated to enable unidirectional perfect absorption/reflection at the visible light spectrum.

Schematic view of the exceptional point on the bilayer metasurface

exhibiting a unidirectional scattering behavior of perfect absorption/reflection.
