dear all,
i am trying to calculate the relative permittivity (frequency dependand in COMSOL 4.4) of a double shell cell, which consists of 4 different layers circulary arranged (2d). The cell is obviously between a pair of electrodes.
Now, my question is, how to i manage to calculate the effective permittivity of all the cell for each frequency.
Thanks in advice

Hey,
I m working on the same kind of problem, trying to determine the effective permittivity of a nanowires array.
For this, I apply an electric field in a specified direction. Then, I integrated the obtained polarization in the direction of the electric field, and do the same with the electric field. Dividing those two quantities gives the susceptibility (you have to correct by a factore \epsilon_0), and then the effective permittivity.
If you look for the effective permittivity in a specified region, the integration has to be done in that region ....
