Hi, Steven, As the previous discussion about [k-point] on the following message,
http://www.mail-archive.com/[email protected]/msg00449.html Is that true that the K-point is necessary when ONLY periodic structure? Say I have a slab parallel to the x-y plane and the norally incident planewave is incident along with -Z direction. The thickness of slab is D in Z direction and size of X,Y is set infinity. refractive index is 2. Component of source is set as Ex. The structure is as attached. It is obviously that no periodicity in Z direction and the PML is set in Z direction. Is that correct? The problem is that should I take X, Y as periodic to set k-point? As I think, every cell in X and Y direction is identical, respectively and the k-point should be set. If yes, how I set k-point? k-point--->(0 0 0) k-point--->(1 1 0) k-point----.(k k 0) The following discussion is talking about the k-point setting as well. http://ab-initio.mit.edu/pipermail/meep-discuss/2007-February/000701.html Cheers Jun
