Generation of Subwavelength Plasmonic Nanovortices via Helically Corrugated Metallic Nanowires
We demonstrate that plasmonic helical gratings consisting of metallic nanowires imprinted with helical grooves or ridges can be used efficiently to generate plasmonic vortices with radius much smaller than the operating wavelength. In our proposed approach, these helical surface gratings are designe...
