无序近场超表面
Disordered Near-Field MetasurfacesDisordered metasurfaces are engineered structures composed of metallic scatterers that manipulate near-field light distributions by controlling the interference of surface plasmons. They enable functions like light focusing and demultiplexing on-chip. / 无序超表面是由金属散射体组成的工程化结构，通过控制表面等离激元的干涉来操纵近场光分布。它们实现了片上光的聚焦和解复用等功能。
