Thanks. I agree...it does become easier to just keep them in the exponential form.. May I ask a bit more of an intricate question? What if we have a slab with a complex refractive index? As in: n = n_1+in_2 How then would you go about expressing the electric and magnetic field?

Yeah, you're correct. I was just confused because of the fact that the transmission and reflection coefficient equal 1. As in: R+T = 1 Thanks for the push. One final question (hopefully): How do I best express the electric and magnetic field, in your opinion, in the 3 different regions? As...

Thank you. I am with you that E_t will have that look at z=0. Just to be crystal clear though: Why ##(1+\Gamma_{1,2})?

Yes. I am talking about a plane wave at normal incidence moving in the +z-direction. The simplest case. As you say, I do not have to worry about an infinite series of reflection nor do I have to make an infinite sum. One bounce back is enough. I am not attempting an experiment, I'm just looking...

Thank you. As you say, it is tedious but straightforward. I have no problem doing it in the case of it simply having a plane wave from one dielectric material to another. But when I have a slab I, for some reason, get stuck. There is no reflective backing I think, but I'm not sure. If there...

Hello. My question/problem is this: I have a plane wave traveling in the positive z-direction through 3 different mediums. Also, medium 2 is comprised of a slab with thickness a. I want to express the electric and magnetic fields of the wave as it travels through these mediums. More...
