摘　　要：Science,373(6559),1133–1137,(2021)https://doi.org/10.1126/science.abj3179 The past few years have witnessed exciting developments in non-Hermitian physics,showing unconventional phenomena and unique features associated with exceptional points(EPs).EPs exist in many open systems,leading to a spectral singularity.The research team from CNRS-CRHEA in France collaborating with the University of California,Berkeley in US utilizes the topological feature around an EP to introduce a novel design in metasurface to achieve a new wavefront phase encoding technique.
