hi! everybody when using meep, I fount a problem when I seting the PML absorbing boundary, I found a problem, when setting whth the below lines
(set! pml-layers (list (make pml (direction X) (thickness pmlthick)))) (set! pml-layers (list (make pml (direction Y) (thickness pmlthick)))) (set! pml-layers (list (make pml (direction Z) (thickness pmlthick)))) the simulation result is different with the below lines (set! pml-layers (list (make pml (thickness pmlthick)))) According the reference of MEEP, Default is putting PML layers on the boundaries in all directions. can anyone can explain this Thank !!
