摘要

利用普通显微镜物镜对方形和六边形纳米孔阵列的背面进行了放大成像，测量了其近场透射率。在这些测量中，可以通过将阵列上的照明光斑强烈聚焦到小于SP传播长度的尺寸来直接观察表面等离子体(SP)的传播。

Direct optical imaging of surface plasmon propagation in nanohole arrays

Measurements of the optical near-field transmission of square and hexagonal nanohole arrays are performed, by making a magnified image of the backside of the hole array with a normal microscope objective. In these measurements it can be observed the surface plasmon (SP) propagation directly by strongly focussing the illumination spot on the array down to a size smaller than the SP propagation length.
