You don't need PML to compute the slab band structure, at least not  
for the band structure of the guided modes.  The guided modes are  
exponentially localized to the slab, so you can just use a supercell  
in the z direction with periodic boundary conditions, and the  
boundaries are exponentially negligible as the supercell size  
increases.  (And in the xy directions it is really periodic, of course.)
