Anisotropic slab periodic boundary condition

shan25_22144

I used PBC to define an infinitely extended anisotropic slab.  I highly doubt the near field results predicted by feko, as the total field is approximately equal to the incident field

 I have attached the CADFEKO model, can you let me know if the PBC are defined correctly.

It seems the properties of the inside anisotropic cuboid was lost.

It seems when you defined the small and larger cuboids, one of them was set to the SEP method and the other to FEM.

After the Union the properties of the inside cuboid was merged with outer (air).

(Sidenote: You don't have to make the unit cell so large. A length or width of about half a wavelength should be ok, but if you make it too small the interpolation will start to break down.)

See attached image of the volume meshes.
