retrieval permittivity permeability branch
Hello ozgur,
I think I've read at least two of the papers you mention. I agree with your caution regarding the assumptions that are made.
That being said, I do prefer the Ziolkowski paper at this point. His points regarding the root branch make sense...
You can do a very simple tunable filter using shunt varactors and inductors in parallel. Reverse biasing the varactors will allow you to move the center frequency.
You can also couple a few of these networks together to produce a sharper rolloff. Another option is to add a gain block between a...

I am working on a similar problem, and you *might* be able to do this if you can perform some mathematical post-processing on the S-Parameters produced by HFSS.
You can find the extraction equations specifically for DNG materials in the following IEEE paper:

I am trying to work with plane wave excitations in HFSS, but I have having some problems.
I can set up the plane wave itself.
I am having problems figuring out how to recover the S-parameters produced by the plane wave excitation. There does not seem to be a port type meant to work...
