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.

Without details about the structure/materials and settings I can only say that, for engineered material such thing can happen, since there might be some resonance or other physics that lead to such results. I would suggest you to check the if the structure and simulation settings are correct. for example periodic conditions and plane wave source should be used. Is the reflection/transmission normal?
