SUMMARY
The discussion focuses on determining the ratio of the lowest TM (Transverse Magnetic) cutoff frequency to the lowest TE (Transverse Electric) cutoff frequency in rectangular waveguides. The user successfully derives the cutoff frequencies for TE10 and TM11 modes but seeks clarification on the absence of TM10 and the implications of the electric field components along the waveguide axis. The consensus indicates that TM modes must have at least one non-zero component, which excludes TM10 in this context.
