Figure 1: Schematic representation of the SBR and geometry of spectral measurements.

The nanocut is introduced on top of the metallic sphere. The incident light is directed onto the SBR from one side facing the nanocut at an angle of 58.5° to the surface normal. Two incident light polarizations are studied: s (perpendicular) and p (parallel) to the nanocut plane. The scattered light is collected from top by a microscope objective lens with 0.55 NA.
