modes cylindrical waveguide
as is well known, a waveguide (take rectangular waveguide for example) is able to support several modes at a single frequency if this operating frequency is beyond the cutoff frequency of these modes.
Here my question is, what determines the very mode that exists in the waveguide if only one mode can actually exist in the waveguide at one time? or what the E and H field distribution should be if those possible modes exist in the waveguide simutaneously?
Thanks!
