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.

Hi Marton, 

You are welcome! These solvers are slightly more complicated to use than FDE, but I am pretty sure you can learn them. If the dimensions, and especially the length of the waveguides are a few microns (only a few times greater than the wavelength), then I will recommend using FDTD. But if these waveguides are extremely long (hundreds of microns), then EME will be more suitable, as FDTD will require a large amount of compute power. Ansys offers short introductory courses on these solvers. You can find them at Ansys Innovation Courses: Ansys Innovation Courses. When you visit the page, you can select the category as "Photonics" to see a list of all availabe courses. From there, you can find both FDTD and EME. These videos are pretty short and easy to understand but I think they will be a food place to get some familiarity with the solvers. The we can discuss setting up your simulation.

Regards,
Amrita
