A propagation TM1 wave in a parallel-plate waveguide of separation a can
be regarded as the superposition of two plane waves, as depicted in Fig.,
where the arrows represents the direction of propagation of the plane wave.
1. What is the angle of incident θ if the wavenumber of the wave is k.
2. What is θ if the propagating guided wave is of TMn mode, n being an
integer ?
