- Because the two sets of field vectors are not all in the same plane, but rather are curved, the propagating electromagnetic wave travels outwards in an expanding shell or balloon-like fashion, kind of like a light bulb on the ceiling.
由於兩組場矢量並不都在同一個平面上,而是彎曲的,是以傳播的電磁波會以一種膨脹的外殼或氣球狀的方式向外傳播,有點像天花板上的燈泡。
- As a quick refresher from before, here's an array of 1280 antennas and we fed them all with the same 12 GHz signal in order to create a laser-like beam propagating perpendicular to Dishi.
簡單回顧一下,這是一個由 1280 根天線組成的陣列,我們向所有天線饋送相同的 12 GHz 信號,以產生垂直於 Dishi 傳播的激光束。

3.8 菲涅爾方程 (3.8 Fresnel Equations)

- We need to talk about One of these cases is something called total internal reflection It turns out that if you have a wave coming from a material that has a high index of refraction So in this case in sub I is greater than in sub T As long as your angles of incidence are small or the the direction of propagation is Is pretty much close to the normal then things come out as you would expect you get a reflected field and transmitted field But as theta I increases and gets bigger as you're going from the material with higher index to the material with lower index essentially the direction case of T of This vector is going to move that way as the incident angle increases and at some point it's going to lie along the surface This means that all the radiation that comes in this direction is going to get reflected You're going to get a hundred percent reflection of the radiation and there's going to be no propagating radiation that goes out and this is called total internal reflection for the obvious reason that the total amount of the radiation gets Reflected from the surface going from a material of higher index into lower index The place this is most commonly used as an optical fibers because this is what keeps the light inside fibers to go very very long distances and Essentially if you want to calculate what the angle is the incident angle is where total internal reflection Starts to occur you simply use Snell's law you basically set theta T is equal to 90 degrees or greater and Essentially you can find that critical angle Let's call it theta C there is given the by the equation the sine of the critical angle is the Insub T the transmitted divided by the incident indices of refraction the second case we've also mentioned very briefly, but that's called Brewster's angle, and that's essentially the point where the Reflection coefficient of the parallel or P polarized electric field component is equal to zero right here in this case You get no reflection whatsoever And so for theta I equal to Brewster angles and Brewster angles given by that equation right there where theta B is Brewster angle so for theta sub I equal Theta sub B.
只要入射角度較小,或者傳播方向基本接近法線,那麼就會產生你所期望的反射場和透射場。但是,隨著θ I 的增大,從高折射率的材料到低折射率的材料,這個矢量的方向會隨著入射角的增大而移動,並在某一點上沿著表面移動。這就是所謂的全內反射,原因很明顯,輻射總量會從表面反射出去,從高折射率的材料進入低折射率的材料。你只需使用斯涅爾定律,基本上設定θ T等於或大於90度,就可以找到臨界角,我們稱之為θ C,它的公式是臨界角的正弦為Insub T,即傳輸的光線除以入射的折射率、在這種情況下,平行或 P 極化電場分量的反射
