scaling factor of PML

Does anyone optimize the performance of PML by parameter sweep of the scaling factor of PML?
If we change the scaling factor of PML, the geometry size of the PML and also the mesh inside is multipled by such a factor, is this correct? What should be the range of this factor?
My problem is that I have a glass substrate in the domain, and I found that the reflection from PML is not neglectable. The PML only works perfectly if the background domain is homogeous.
If anyone have optimized the performance of PML by those factors, I would very happy to discuss with him.

Hi
indeed PML assume a material if you set air and you end with glass you will have some reflections, ideally you should match the environment accordingly for best results

Good luck
