- 本文证明了利用三维渐变折射率透镜减小光束发散，可以使轨道角动量（OAM）无线电链路的作用距离至少增加一倍。这是朝着使用廉价、紧凑和重量轻的透镜实现实用的高容量OAM无线电链路迈出的重要一步。
— This paper shows that the range of an Orbital Angular Momentum (OAM) radio link can be at least doubled by using a 3D graded index lens to reduce beam divergence. This is a major step towards realizing practical high capacity OAM radio links using cheap, compact and light weight lenses.
