Hi, I'm doing a question using the Fresnel power coefficients, not the Fresnel amplitude coefficients. We can use matlab for this, but we are given a fixed angle of incidence of 45 deg so its really just one calculation, as opposed to an earlier question where the angle varied between 0 and 90 deg. We are given the refractive indices. But what are these equations, lol. We're supposed to look them up but I can't find them. The earlier question talked about the Fresnel amplitude coefficients, and this current question tells us to use the Fresnel power coefficients so I assume they are different. Thanks a lot Liam
I've never heard of Fresnel power coefficient, but I guess it's similar to reflection coefficient. Then if you can calculate the relation between amplitudes, since power ~ intensity ~ amplitude^2, you can calculate the coefficient, right?
Hi Thanks, yeah all we had to do was square the Fresnel amplitude reflection coefficient to get the power reflection coefficient and use 1-R^{2} to get the Fresnel power transmission coefficient.
