Figure 7
(a) Sketch of a surface modulated with isosceles triangles. It is sufficient to simulate one repeating unit due to the periodic boundary conditions. (b) Comparison between the analytical absorption corrections calculated by Borie (1981) (solid line) and the simulated absorption corrections (points) on a triangular modulated surface with a slope angle of 45° for variable heights μh. The results are in good agreement apart from the discontinuity at θ = 18.4° which is discussed in the supporting information. |
