I have measured electrical conductivity of a material by using impedance spectroscopy (IS). The obtained data from semi-circle of Nyquist Plot is resistance (Z). I am wondering that can I calculate dielectric constant from this data?
Dear Friends here with I attach my excel sheet for the impedance, modulus and dielectric calculations. kindly refer it. For more understanding you may refer my papers attached herewith.

Hi Wirat,
You can calculate the dielectric constant of your material using the IS data. You need to calculate the capacitance of your system from the impedance by taking into account the effect of series (contact) resistance and parasitic inductance if necessary. If you know the capacitance and the geometrical dimentions of your sample you can easily calculate the dielectric constant at any frequency. You will find some useful information in this paper:

Dear Dr Brus
Does it mean the capacitance can be obtained (in Zview--for example) by fitting semi circle? I did put R and C in a series circuit when I fitted a semi circle and the intercept is Z.
I really appreciated your help and looking forward to hear from you.
Best regards, Wirat
Hi Dr Kumar
Thank you so much I think I know how to do now.
Best Wirat
give me your email i can send you the sheet for such calculation probably that will help you.
Hello Jaydeep, I also have the same question as Wirat, may you please e-mail me the sheet as well on [email protected].
Thank you
Hello Jaydeep, I also have the same situation as mentioned Wirat , may you please e-mail me the sheet as well on
Prof. Jaydeep, I have the same question as Wirat, please e-mail me the same to [email protected]
Dear Professor @Jaydeep Joshi
Would you please send me the calculation for dielectric constant via my email; [email protected]
Thank you
Dear Professor Jaydeep Joshi
Please, could you also send me the sheet for the calculation of the dielectric constant via my email; [email protected]
Thank you
Dear Prof Jaydeep Joshi
Would you please send me the calculation for dielectric constant via my email

Can you please send me the sheet for dielectric const. calculation too ?
My email - [email protected]
I also want to know if we can calculate the capacitance & conductance of the material at each frequency.
Thank you

One quick question :
The thickness and radius we need to know for dielectric const. calculation at each each frequency is the thickness and radius of the working electrode only , right ? And the area is simply piR^2 ( working electrode being circular in my project ) . Please clear my confusion . Thank you again for your immense help.
The thickness and area of material which you are using not the working electrode. The material through which current is passing.

I would like to know the complex dielectric constant depends on the thickness of the materials between two electrode if the method is parallel plate. So if the thickness is changed the value of real and imaginary part of dielectric constant will be changed. Or dielectric properties is material properties, it is not depending on the thickness of materials. Thank you.
Madam
It is intrinsic property of materials. The capacitance value depends on thickness of materiel.

Is there any way to calculate dielectric function of non metallic particles using dielectric function of the bulk material?
There is relationship between Z* and all the other complex electric and dielectric parameters according the following eqn.:
Z* = iwCo(Eps*)
Dear Farsad
the attached file, contains the data to measure and the equations to use to get the desired info.
Kind regards
