Figure 5From: Fabrication and characterization of well-aligned plasmonic nanopillars with ultrasmall separationsMeasured absorbance of Ag nanopillar arrays with 485- and 540-nm periodicities and 35- and 40-nm inter-pillar separations. The insets show the schematic diagram for experimental characterization at normal incidence and the electric field distribution at plasmon resonance.Back to article page
