Simulated diffraction from a slit with corrugations. (a) The near-field and (b) propagated distributions of the magnetic field amplitude |H y | in the neighborhood of a slit surrounded by corrugations. (c) The field propagating towards and past the image plane z = 0 in an Abbe configuration with numerical aperture 1.4 and magnification × 10. The complete field probe with the slit surrounded by corrugations is considered.
