Not sure if the AWR EM simulator can do this or not...
You could do this with Sonnet Lite by using a "General" metal type, and assigning an Xdc value that gives you the same reactance as the kinetic inductance. It's only going to be valid at one frequency, so if it varies a lot with frequency you'll need to modify Xdc and resimulate at each frequency.
The full version of Sonnet has a kinetic inductance metal definition under the "General" metal type, but it's grayed out for Sonnet Lite, so it must not be available for the free version.
Good luck,
