Hi, Sophia, as far as I know, it is possible to overlap any material
with PML. The PML condition however applies for the whole boundary, so
it can not be defined in its part only.
Note I had some numerical stability issues when the PML was defined on
one axis only while the other boundaries were periodic. The
nearly-grazing incidence waves could be slightly _amplified_ by PML.
This problem never happened when the PML was at all boundaries, nor it
happened when the structure was defined with sufficient losses.

Hello,
I was wondering is it at all possible to have material on top of the
PML? The reason I ask is I'd like to only have part of the PML along
the same axis...
