The problem is:
1. Assume ONE BOX W*W*H1 filled with a dielectric material with dielectric constant eprs. The vertical walls are assigned periodic boundary conditions and the other two faces are Floquet Ports (One TE mode and one TM mode).
2. Assume a transmission line that is L1 long with a characteristic impedance of Z1, and a propagation constant beta.
Q: Is there an analytical relationship between the two? I.e. can one represent the unit cell by a transmission line?
I tried to check this in HFSS, (FEM for the box and Circuit for the TL) and it looks like the answer is NO.
I hope I'm wrong because I need to do the analysis of a stack of 161 unit cells each having crazy dielectric constant (negative, less than 1 etc.). It's my modeling of a plasma sheath for which I need to find the transmission loss.
