Enhanced optical transmission: Role of the localized surface plasmon

Shan Wu, Qian-jin Wang, Xiao-gang Yin, Jia-qi Li, Ding Zhu et al.
We report the observation of enhanced optical transmission through the metal subwavelength hole arrays with nanoparticle inside the hole, and demonstrate the transmission enhancement and the suppression due to the excitation of the localized surface plasmon (LSP). We interpret this phenomenon with t ... [Appl. Phys. Lett. 93, 101113 (2008)] published Fri Sep 12, 2008.
