[領域] 電磁波／電磁學 (題目相關領域) [題目] 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!! -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 114.41.215.252
