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 Amrita,

Thank you for the reply. In that case I have a related question. I'm currently doing simulation times of 30ps, stabilized boundary 30PML layers. However, when I use a narrow wavelength spacing (e.g less than 10nm), or I add a custom (n,k) import, I get oscillations in my dipolepower and transmission. My thought is that since the dipolepower monitor is placed at the center, the oscillations could be caused by reflections, or PML relfections. Additionally, I also see these oscillations in the transmission outside the photonic crystal. What could be causing those oscillations in power?

Example below is for custom (n,k) import
