Figure 5
Calculated diffraction efficiency of two identical stacked gold FZPs with an outermost zone width of [\Delta r] = 100 nm, a zone height of h = 500 nm each and a photon energy of 6.2 keV. As the separation distance ld increases, the diffraction efficiency of the two stacked FZPs decreases. The diffraction efficiency of a single ordinary FZP with the same parameters is shown for comparison.  [article HTML]
