Plasmonic Lens |
| 摘要 |
A plasmonic lens is presented comprising a surface for interaction with an input electromagnetic field, wherein this surface has a pattern comprising an arrangement of a plurality of elongated spaced-apart features of a predetermined geometry arranged in a spaced-apart relationship along at least one segment of a spiral curve, each of the pattern features defining an elongated interface for creation of surface waves in response to the interaction with the incident electromagnetic field, such that the pattern provides linear-polarization-independent plasmonic focusing and large area, high contrast, circular polarization dichroic plasmonic focusing. |

1. A plasmonic lens comprising a surface for interaction with an input electromagnetic field, wherein said surface has a pattern comprising an arrangement of a plurality of elongated spaced-apart features of a predetermined geometry arranged in a spaced-apart relationship along at least one segment of a spiral curve, each of said features defining an elongated interface for creation of surface waves in response to the interaction with the incident electromagnetic field, such that said pattern provides linear-polarization-independent plasmonic focusing and circular polarization dependent plasmonic focusing of the electromagnetic field incident on said pattern. |
