耦合等离子体薄膜-纳米粒子系统在模式杂化时可以实现光吸收和大的电场增强。本文首次报道了纳米棒二聚体等离子体超材料中暗等离子体激元模式与表面等离子体激元极化之间的耦合效应。耦合系统可以实现近乎完美的吸收和极大的场增强，这为设计用于检测单个分子的高性能表面增强芯片提供了新的见解。
The coupled plasmonic film-nanoparticles systems can realize the optical absorption and large electric field enhancement when modes hybridize. In this paper, we report, for the first time, a coupling effect between dark plasmon mode and surface plasmon polaritions in nanorod dimers plasmonic metamaterial. Near-perfect absorption and extremely large field enhancement can be achieved in coupled systems, which provide a new insight to design the high-performance surface enhanced chips for detecting individual molecules.
