How to enter complex conductivity material model in EmPro

Question asked by carbon9 on Aug 4, 2014
Hi,

I have frequency dependent complex conductivity data of a metamaterial and need to enter it into EmPro new material properties. My data is as follows (first few lines)

sigma=sigma_r+i*sigma_i (complex conductivity)

f (GHz)*****sigma_r*******sigma_i
              
0********* 5E4********** 4.5E3
0.5********5.4E4********4.7E3
1**********5.92E4*******4.87E3

How can I enter these values? In the edit new material properties box, "sampled" selection seems the most suited one to my data but there it wants Conductivity and relative permittivity. It doesn't permit to enter frequency dependent conductivity, only accepts real valued conductivity data. How can I enter my frequency dependent complex conductivity data in EmPro? Is there a way to convert my complex conductivity data to a form EmPro accepts?

I really appreciate your help. Thanks in advance.
