I am trying to simulate Rayleigh scattering. Computational cell is 4 * 4 * 10 (x,y,z correspondingly) , scatterer is in the center, resolution 20. Incident planewave generated as volume source at z=2 propagating along z, with Ex and Hy polaization. Here comes the problem - I can set up PML only on both sides of Z. If I set PML on all sides, planewave gets ugly, but if I don't set PML on X and Y sides - scattered fields reflect at boundaries, create wrong pattern and decay much slower than incident wave.
I belive that this is because of way how planewave was created , I did it as found in mailing list archive (single gaussian envelope volume source) . AFAIK this approach is valid only for incident planewave with periodic boundaries on X and Y, and pml in Z. So how can I overcome this problem - create a planewave inside a box with PML on all sides ? I found messages mentioning several point sources with crafted parameters, but no details on it.
