光子自旋解耦合的人工表面等离激元双功能波前调控

Abstract

Objective In the realm of nanophotonics, the discovery of a geometric phase solely dependent on the rotation angle of metasurfaces has catalyzed a flurry of research activity. The breakthrough has facilitated the development of avantgarde scientific and technological applications, such as metasurface microscopy and compact spectrometers. However, a pivotal
