摘要

Researchers at State Key Laboratory for Mesoscopic Physics and Department of Physics, Peking University (PKU), have recently shown that an otherwise forbid-den longitudinal surface plasmon mode of a gold nanorod can be excited by nor-mally incident linearly-polarized light if it is coupled with a nanoparticle with proper plasmonic resonant frequency, volume, and composition[1].
