介绍了多色等离子体激元的概念，提出了一种用于表面等离子体激元纳米聚焦的宽带等离子体激元透镜。该透镜采用抛物线调制的金属-电介质-金属结构。这种等离子体透镜具有大于光学倍频程的带宽，从而为宽带等离子体应用开辟了新的机会。
We introduce the concept of polychromatic plasmonics and suggest an broadband plasmonic lens for nanofocusing of surface plasmon polaritons. The lens employs a parabolically modulated metal-dielectric-metal structure. This plasmonic lens has a bandwidth of more than an optical octave thus opening new opportunities for broadband plasmonic applications.
