Hi,
You need to include the glass slab into the PML. That is, if sx, sy are the
sizes of the computational box in the x and y direction and you have
propagation along thex direction.
In the case that you dont add PML in the x direction you have PEC boundary
conditions which enforce mirror symmetry for the electric field.
Therefore, you effectively have an infinite slab, which is valid in this
case.
(set! geometry-lattice (make lattice (size sx sy no-size)))
(set! geometry (list
(make block (center 0 0) (size thickness sy infinity)
(material (make dielectric (epsilon 12))))))
(set! pml-layers (list (make pml (thickness 1.0))))
