IntegralGISAXS

Wen-Li Wu (NIST) developed a more direct method for simulating GISAXS (as compared to DWBA) wherein one considers the ideal reflectivity curve for the sample, and then computationally solve the associated integrals.

  • IMPORTANT ERRATUM: In equation (20), there should be a "+" in between $\mathbf {\tilde {R}} (-k_{s},-k_{i})$ and the following term (prefactor times integral).
