3. Consider a rectangular waveguide, with cross-sectional dimensions L, and L Explain why it is possible, for specific values of Lx and Ly, to have degenerate cutoff frequencies (i.e., why it is possible to have two different sets of integers {m,n) and {m,n such that ω㎜ = am+). a. b. Suppose L-2L. Find a set of degenerate cutoff frequencies.
