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.

Hello,

I would also like to provide further information regarding convergence tests. Previoulsy I tried to simulate a high-Q mode supported by the structure. Now, I look into a lower-Q mode supported by the structure, and I have been able to reach the convergence conditions for the RCWA simulations. For this lower-Q mode k=1600 and k=2000 yield identical results. However, these do not match the converged results of the FDTD simulations (see attached images). Is it possible that this is the best achievebale matching between RCWA and FDTD and it is not possible to improve the result further?
