Modellign of a frequency dependant resistance ATP

Hello everyone,
I am currently working on the modelling of a multilayer round conductor and I would like to implement it in ATP.
The main non-linearity of the device studied is for the resistivity, for which I made analytical calculations and found a simple enough frequency-dependant curve by interpolation. (Note that the calculations are made in sinusoidal regime).
Does anyone have any suggestions about how to implement this in ATP ?
My idea was to use a variable resistance (R(TACS) Type 91) for series resistance and "manually" draw a PI-model of a line in which capacitance and inductance can be ketp constant (low frequency variation for the inductance and the device should be no longer than a few meters).
As you can understand now, the model used for the resistance is the major component here. So is it possible to compute an instantaneous frequency of the incoming voltage wave in the model by a time-corrected instantaneous frequency algorithm, then used inside the model to calculate the resistivity ?
A transfert function may probably suffice too but I am not sure about it and which signal to use as an input for it, as I am quite new to ATP.
The problem studied might be close to the modelling of a cable/line in which skin effect is considered.
Thank you very much for your answer,
Sincerely,
Fran?ois Galliano
