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 your responce. The sphere radius is 0.0175 um, centered at 0, 0, 0 um. The simulation span is 1 um for x,y and z, and is also centered at 0. The boundary conditions are all PML. The source injection axis is z-axis, and the span is 0.148 um for x, y and z. The mesh override region has dx=dy=dz=0.001 um, and geometry x span = y span = z span = 0.152 um. The source injection axis is z-axis, and geometry x=y=z span=0.148 um. The DFT monitors are 0.152 um span in each direction. The absorbance group geometry is 0.144 um spans, and the scattering is 0.152 um spans. Here is a screenshot of the overall geometry.
