Impedance spectroscopy of two electrodes in medium with frequency-dependent conductivity and permittivity

Please login with a confirmed email address before reporting spam

Hello,

I have created parameters and tried (in the material water,liquid) to replace the preset electrical conductivity and electrical permittivity with formulas to make them frequency dependent (because i want to simulate NaCl solution). This does not seem to have worked well, is there any other way in the program to account for the frequency dependence of the medium?

I am currently using the electric currents setting but it is not giving me the results I want. I had hoped that the electroanalysis would give better results but I can't find a way to display the impedance between the two electrodes. I cannot use "Electrode surface" because my electrodes are in the medium. What settings do I need to make to get an impedance spectroscopy?
