Hi Steven,
>I don't have any particular plans to support that object. Of course, you >could simulate it just by creating a bunch of blocks, and in general >adding shapes that can easily be simulated by a finite number of existing >objects is not a high priority... (However, at some point I would like to >add support for compound objects, e.g. an object with a hole punched >through it, as opposed to a hole punched through every object beneath it >too. This would make it easier to do what you are suggesting.) > >However, I should mention that what you suggest does *not* necessarily >sound like a good idea for PML regions. You want PML to overlap your >structure, not a different uniform material. If the PML doesn't overlap >your structure, there will be reflections at the edge of the PML where the >structure changes. > >Steven I was thinking about the case of periodic structures with defect, when using geometric-objects-lattice-duplicates it fills the entire supercell but the array must not overlap the PML or is that not an issue?
