I have tried below measures but nothing has worked so far!!! I have calculated it analythically and want to compare my simulation results with the analythical calculations.&lt;\/p&gt;&lt;p&gt;1-Since, I am simulating a finite thickness line, I have defined the superconductive&#8217;s bulk conductivity using two-floid model complex impedance as a function of temperature and frequency.&lt;\/p&gt;&lt;p&gt;2- Since the waveport does not accept a complex impedance, therefore I have added a PEC line in contact with the port and then connected it to the superconductive line and then deembeded the port to the location of connection of PEC-superconductor. This returns the PEC&#8217;s characteristic impedance! I then set the post processing impedance to be normalized to the complex value of the superconductor&#8217;s impedance but did not work again!!!!&lt;\/p&gt;&lt;p&gt;3- I have tried the ports only setup but did not work!!!&lt;\/p&gt;&lt;p&gt;4- I have used the lumped ports and set the impedance as the superconductor&#8217;s complex impedance in the original port impedance and the post processing renormalization. Neither worked!!!!&lt;\/p&gt;&lt;p&gt;5- I am using the field calculator, but since field calculator calculates the characteristic impedance in a single frequency, it does not work!!! I have used python scripting in HFSS again didn&#8217;t work!!!!! Even that single point that the field calculator obtained is not correct!!!!!!!!!!!!!&lt;\/p&gt;&lt;p&gt;I appreciate ANY KIND OF HELPS!&lt;\/p&gt;&lt;p&gt;Thanks!&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-397478","topic","type-topic","status-publish","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 4.9.10 - aioseo.com -->\n\t<meta name=\"description\" content=\"Hi All,I am simulating a simple superconductive coplanar waveguide on silicon substrate in HFSS.
