[期刊论文] 作者：OuboYou,BenfengBai,XiaoweiLi,
来源：ChineseOpticsLetters 年份：2014
We present an experimental study on a unidirectional surface plasmon polariton (SPP) launcher based on a compact binary area-coded nanohole array, where the symmetry breaking is realized via effective-index modulation in the binary pattern ......
Tunable directional beaming assisted by asymmetrical SPP excitation in a subwavelength metallic doub
[期刊论文] 作者：XiaoweiLi,QiaofengTan,BenfengBai,GuofanJin,
来源：ChineseOpticsLetters 年份：2012
We present a design for tunable directional beaming through a subwavelength metallic double slit surrounded by dielectric surface-relief gratings. On-axis and off-axis beaming can be switched by controlling the incident angle to asymmetrica......

来源：PhotonicsResearch 年份：2020
With the recent development of the metasurface, generating an optical vortex in optical far or near fields is realized in various ways. However, to generate vortices in both the near and far fields simultaneously is still a challenge, which......
