I don't think the time domain is the cause. If it were, it doesn't explain why the X and Y axis does this, while the Z axis, alone, does not. I would still expect a dipole on any of the axis in free space to create the same pattern in relation to the dipole, and expect that pattern to have the same properties throughout. I don't see how the time domain would explain or resolve this.

That being said, I don't have access to FDTD modeling either. As far as I have found until recently, most FDTD modeling was done with Matlab, which is even further out of my price range than some other options. Although I have noticed a python extension for FDTD, and I do have some very limited python programming experience, but I haven't played with it yet.
