Hi,

I need to calculate an axisymmetric structure.So I use 2D axisymmetric model.But I found PML in cylindrical axis didn't work well.The structure is a silver circule disk surrounded by PML.Reflectance is serious.How to improve the performance of PML?

PS:The source is set on one plane of PML and is axial symmetrical,thus cylindrical PML is better than sphere PML in this case.

Thank you
