3.8 菲涅爾方程 (3.8 Fresnel Equations)

This is not an equal sign this essentially says the in the complex index of refraction Essentially is related to alpha and beta, but is not equal to alpha and beta So let me just clarify that since that's a mistake in the slide Now if the material is very lossy or if it's something like a metal then then most of the incident radiation is going to be Reflected, but if it's a dielectric material then the transmitted wave which essentially has a k vector K sub T here is coming in a different angle So theta sub T is not necessarily equal to theta sub I or theta sub R the transmitted wave goes in a different direction than the incident wave and the reflected wave and We can calculate the angle of that transmitted wave using something called Snell's law, which is given right here that the the Index of refraction in I of the wave coming in times the sine of the incident angle incident angle is equal to the index of refraction for the material the waves getting transmitted into times the angle of the Transmitted wave so if we know in sub I in sub T and the incident angle theta we can do a simple algebraic manipulation to calculate the angle of transmission And so those really are the basics of waves and incident on surfaces if you understand these basics the rest of it Although there are some long equations follows pretty straightforwardly now the first complication we run across is that the Reflection and transmission that we see depend on the direction of the electric field And so the first direction of electric field we're going to talk about is called s or perpendicular Polarization and the way we we define this is we think as we've talked about before of a plane of incidence and this plane of incidence is the plane that contains both the incident and the In the plane of incidence the normal to the surface lies in the plane of incidence and if the electric field is sticking up out Of the plane of incidence so there's essentially a 90-degree angle Between the electric field and the plane of incidence then we call it s or perpendicular polarization where perpendicular means It's perpendicular to the plane of incidence Now if the electric field is perpendicular to the plane of incidence We can calculate the magnitude of the reflected field and the transmitted field given the magnitude of the incident field so essentially this incident field is going to come in like this some of its going to bounce off and there will also be an electric field pointing in the same direction that we're going to call e Sub r or the reflected field and the relationship between the incident field e sub i Right here and the reflected field e sub r right here is The reflected field and notice we have this little perpendicular sign that says it's perpendicular to the plane of incidence is equal to the coefficient r perpendicular times the the incident field and Essentially without deriving it the reflection coefficient for perpendicularly or s polarized radiation is given by this it depends both on the incident index of refraction the index of refraction of the material that the waves reflecting from are getting transmitted into and the cosine of both the incident angle and The angle the waves being transmitted at and remember Snell's law says in sub i sine of theta sub i is Equal to the index of refraction of the material that the waves getting transmitted into Times the sine of that angle and so we calculate theta sub t from this equation right here So overall this gives the reflected field Once we know all of these things similarly, there's going to be an electric field pointing in the same direction That's transmitted into the material We can call it e sub t here and the relationship between the transmitted field and the incident field is given by a very similar expression, but we use the term t perpendicular for the We find it depends on the incident and transmitted indices of refraction the incident and transmitted angles And if we plug it into this equation, we'll know what fraction of the electric field gets transmitted in other words the ratio Between the incident field the magnitude of the incident field on the transmitted field and because they're vectors the vectors are going to point in the same direction Now I'm using a lot of Lines here, but we have to remember that these are actually waves coming in as shown in the bottom figure down here So they oscillate up and down and they're plane waves So we assume that everywhere on these planes that are represented by these little green squares The electric field is a vector field the vectors all point in the same direction But that direction can vary with time and space as we saw in previous talks And again, the angles are just given by the K vectors K incident K transmitted K reflected we have exactly the same situation or very close to the same situation if the Notice that instead of the electric field pointing up and down like before Perpendicular to the plane of incidence now the electric field lies in the plane of incidence and we call this P or parallel polarization Because the electric field is in the plane of incidence.
這不是一個等號，本質上說的是復折射率，本質上與α和β有關，但不等於α和β，所以讓我澄清一下，因為這是幻燈片中的一個錯誤、我們可以利用斯涅耳定律來計算透射波的角度、是以，如果我們知道子 I 子 T 和入射角度 theta，我們就可以通過簡單的代數運算來計算透射角。所以我們要討論的第一個電場方向叫做垂直極化，我們定義垂直極化的方法就是我們之前討論過的入射平面，入射平面是包含入射和透射的平面，表面的法線位於入射平面內。如果電場垂直於入射面，我們就可以根據入射場的大小計算出反射場和透射場的大小。入射電場會像這樣射
