Hello Francois,

ω for the pulsation and ω = 2.π.f
Ω for ohms

But you used R/Ω (in "S11 R/Ω & X/Ω"), so I repeated that (did not want to
introduce something new), but indeed it is R/ω

When it happens at home, I read
Now Z = C* Ω* ( mu'+j*mu")

I understand
Z = Cω (mu'+jmu")

Correct.

You said
The C is depending on the physical layout of the toroid (and constant for
that toroid).

Ok but what is m ? why 'm' is not in C as
Z = Kω (u'+ju") ??

mu is the greek letter μ (so not m*u;-)

You have write :

Z is measured by the nanoVNA. By dividing the Z by , you get a value

that is:

Z' (=Z/ Ω ) = C* ( mu'+j*mu")

I supose
Z' = Z/ ω = C ( mu'+jmu")

Correct: Z' = Z/ ω = C ( μ '+j μ ")

Z is calculated by the nanoVNA thrue S11 i suppose

What do you do with Z'

Z' is also calculated by NanoVNA Saver (it is whe graph you did/do not
understand: Z/ ω ).

Do you plot Z' as a function of ω ?

Indeed, NanoVNA does that for you.

All the best,

Victor
