Thanks GOTWW for the insight
However, the mode I have (which I'm pretty sure is TM01) has a radial e-field pattern, not circular.
I'll try & track down the MIT radiation labs titles again...
thanks
Hi
I have a circular waveguide which can propagate both TE11 and TM01 modes due to its diameter. I would like to be able to suppress the TM01. Are there any easy classical ways of doing this? I cannot make the waveguide any smaller by the way...
thanks
