WebThe numbers m and n correspond to the number of wave halves present in the waveguide walls of dimensions a and b, respectively. The mode index is applicable to the two modes of wave propagation possible in a rectangular waveguide (TE and TM mode). Every combination of m and n defines a mode in a rectangular waveguide except (0, 0). WebThe only way for the condition in [10] to be true for all values of x and z whenever y=b, we must have: If this is to be true everywhere, c3 could be zero. However, if c3 is zero (and we have already determined that c4 is zero), then all of the fields would end up being zero, because the function Y (y) in [7] would be zero everywhere.
