Hello, I am trying to model metatmaterials using perfectly matched layers with the physics Ectromagnetic Wave Frequency Domain. Specifically I am trying to see the scattering effects from a spherical nanoparticle.
I was wondering which geometry would be better computationally for the outer boundaries of my model.
Based off of my limited testing it seems the sphereical outer boundary takes longer but I do not know why.
I know the sphere would take up less volume but I was wondering if the sphereical shape might cause problems with the perfectly matched layers.
