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.

Regarding the example of the Mach Zender interferometer, I indeed see the slight asymmetry in the electric field distribution at 0 V and 6.5 V. Do you think this asymmetry is physical or a result of the numerical error? As seen above, this asymmetry becomes very dramatic when the silicon pad is replaced with a dielectric material with the same DC permittivity. Why is there such a dramatic difference between results observed in the two simulation setups?
