i'm stuck with relationship between s parameters and permitivity and permeability
can smbody help?

Hi,

it is not so easy for this forum,

so S11 is about wave impedance and return loss

http://en.wikipedia.org/wiki/Electromagnetic_impedance

http://en.wikipedia.org/wiki/Return_loss

and loss (S21-S11) is not about ε and μ, it is about σ and tan δ (exactly complex permitivity and permeability

I hope, that I have true :D and that I helped you

Thanks a lot

actually i want to reach permitivity and permeability via s parameters thru impedance and refractive index :)

I think that this R&S application note is more useful for you.

thanks aloy nccu , surely they r going to help me
