1. 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(向量), where <u> is the average energy
density of EM fields.
希望有詳細的計算過程~感謝!!
