How to get the even and odd mode by HFSS

Dear Sir:

As you said, I cannot use voltage source to get the Spara. But how can I get the even-mode and odd-mode of a coupler due to no definition of sign of voltage by HFSS?

Thanks a lot!

Regards,

Wei

When you assign a waveport which includes two or more conductors, you can pair them for even-odd mode excitation.

I would recommend you to get some examples and slides from Ansoft homepage and try them first.
