Analogy between EM wave reflection and S-parameters

[QUOTE="paralleltransport, post: 6564885, member: 589748"] I see, thank you. In fact you're right. I checked a calculation I made of the transmission of a plane wave across a thin metal barrier with a certain conductivity. This is a problem in Jackson E&M. I tried to solve it 2 ways: - the correct way matching boundary conditions at the interface (PDE style) - The incorrect way by summing all transmission on a lattice diagram using the famous (2n2)/(n2+n1) transmission coefficient and reflection coefficient (n2-n1)/(n2+n1) The 2nd answer did not match the first. I don't have a good argument under what conditions should the 2 answers match however. My guess is that when the loss is low and the metal barrier is think, where the eikonal (or WKB) approximation to wave propagation is correct, the PDE solution and summing all reflections as a geometric series will match.
