Hi,
You can find information concerns how to define the PML in comsol in this link:

information about PML are explained in page 8 and 9.
Faycel,
Hello,
If you model a spherical or a cylindrical magnetic shield, subjected to a harmonic magnetic field, you can model only a quarter of it. The field domain can be a square.
On the left and right sides you should impose Electric insulation (n x H = 0).On the bottom side magnetic insulation (Az =0) or magnetic potential and choose Az = 0.
On the top side you should introduce the source of the magnetic field by specifying the value of the magnetic potential ( Wb/m).
After solving you choose from Postprocessing, plot parameters and choose Contour, magnetic potential Az. The lines should be straight lines, from left to right ( without the shield).
