Paper Abstract

In solar control devices based on total internal reflection and microstructured surfaces, the Goos-Hänchen shift can lead to a significant decrease in the geometrical optical solar shading effect. The knowledge of the maximal size of the Goos-Hänchen shift for a specific geometry is an important information to estimate its effect on the desired function of the system. Quantitative measurements of the shift for optical wavelengths seems not feasible and analytical approaches are not suited to identify the maximal shift. By using newly developed numerical techniques, namely the rigorous coupled wave analysis (RCWA), the maximal Goos-Hänchen shift for given parameters can be determined.
