We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

You can use script to get grating characterization. and the result:

gc=getresult("RCWA","grating_characterization");

Rss=gc.Rss;

etc

are actually the amplitude results, S parameters similar to Fresnel coefficients. They are complex and has the phase you need.
