WebOct 1, 2024 · In [22] we applied the (e,m) theory [26] to calculate external diffraction by an isometric hexagonal prism. Seeking clarification on the applicability of the (e), (m) and (e,m) theories, we now investigate these three approaches for the same case.Prism height, edge length of the basal facets and wavelength are 10 μm, 5 μm and 0.5 μm, respectively. WebNov 30, 2009 · Theory and experiment analysis show that diffraction patterns at 1/6 and 1/3 Talbot distance are consist of nine equally spaced copies of the original aperture, and each copy is shifted by 2a and a (a represent the side length of the hexagon) from another copy, respectively. Experimental results are in good agreement with the theoretical analysis.
