empossible.netWhat about the TE10mode? TE 1, 010 mn 22 c,10 11 0 1 22 f aba CAUTION: We cannot yet say that the TE10is the fundamental mode because we have not checked the cutoff frequency of the TM modes. Since a > b, we conclude that the first‐order mode is TE10because it has the lowest cutoff frequency.
