I am trying to make some structure shown in the attach picture. This structure should have uniform near field magnetic field on one side of it.
As it is differential mode, so I was trying to use driven terminal. But when I set the wave port, it says that no conductor found on the port. I am sure I set the material right and there do is conductor connected to the port. So what is the problem here? Need help8-O. THANK YOU.
Is this structure some kind of left hand material??

If the conductor are made just striplines, this problem wont come out.
But this loop-line structure will have this problem
so what is the problem indeed?
I also met the situation that one of the two port was set successfully but the other failed.
