Consider a TM(n) mode of propagation along the z
direction in the space between parallel conducting
planes
(a) Show that as the frequency ω approaches the
cutoff frequency the wavelength for that mode
approaches ∞.
(b) Show that the averaged Pointing vector <S> =
<u>vg ^z, where <u> is the average energy den
