Hi all,
I'm trying to simulate a circular waveguide in CST. I have drawn my cylinder, picked the end faces and added waveguide ports to them.
I want to excite this with circular polarization, do I do this by defining a plane wave from the menu and selecting circular from the option?
When I simulate, I get a warning message that says, "2 degenerated mode(s) at port 1 is/are not included in time domain calculation! It may be better to increase the number of modes at port 1."
Can anyone explain this to me? I have increased the number of modes up to 20, and I still get this warning! This is with no CP plane wave, just the default excitation (which I assume is linear)
Thanks.
