Figure 7From: Free-field characterization via directional transmission through a nanoapertureSimulated diffraction from a slit without corrugations. (a) The near-field and (b) propagated distributions of the magnetic field amplitude |H y | in the neighborhood of a single slit in the Al screen. (c) The field propagating towards and past the image plane z = 0 in an Abbe configuration with numerical aperture 1.4 and magnification × 10.Back to article page
