The text I am referencing is Fundamentals of Photonics 2nd Ed. by Saleh and Tiech. They give the Fresnel equations as: $$ r_{TE} = \frac{ η_2*secθ_2 - η_1*secθ_1 } {η_2*secθ_2 + η_1*secθ_1 }, t_{TE} = 1 + r_{TE} $$ $$ r_{TM} = \frac{ η_2*cosθ_2 - η_1*cosθ_1 } {η_2*cosθ_2 + η_1*cosθ_1 }...

Thank you Charles, but I don't mean the reflection coefficients for the magnetic component of a TEM wave. I mean a TM polarized wave, that is to say, my wave doesn't have a magnetic field in the direction of propagation. It is also called a parallel polarized wave or a p polarized wave. I'm...

The complex amplitude ratios for light are defined as: rTM = ErTM / EiTM tTM = EtTM / EtTM I've done the derivation from Wikipedia and see that (n2/n1) * tTM = rTM + 1. But I don't understand what is going on physically. I understand that these values are not power or intensity so I can't...

Ah thank you! This helps my understanding a lot!

I have a pretty good understanding that when polarized light is incident on a surface it will change handedness (Right handed polarization, to left handed polarization for example) and remains will remain circular if it is incident at an angle less than the Brewster angle, otherwise it will...

I'd like to say hello! How is everyone doing?
