I have a question about complex reflection and transmission coefficients. For example, I am modeling a wave in air (medium 1) ## \varepsilon = \varepsilon_0 ## reflecting on, and transmitted to, a medium 2 with ## \varepsilon = \varepsilon' -j \varepsilon'' ## If the wave would have traveled...

Yep, but the statement was: "If E and M are not in phase then it must be propagating through a material with complex impedance. The EM wave will then be in a dielectric or a magnetic material." So I think Baluncore meant conductive.

Thanks! You mean 'The EM wave will then be in a conductive or a magnetic material'?

You're right, but I am processing data that have partly traveled trough some conductive media before received back to the satellite as backscatter. I guess definition of the question is actually harder than I thought :-).

I mean 'and from the measured induced current derive the electromagnetic E field. Or is it something else I might define incorrectly? Another way to ask this question is: can a radar antenna measure a phase-shift between the H and E field (where the H field lags the E field)?

Hi there, Maybe this is a stupid question. Maybe not. I want to make a statement in my thesis that says that all radar antennas on satellites derive the EM field by: receiving the time-varying H field, and from the induced current derive the EM field. Am I correct in saying that? Or are there...
