Can frequency-dependent material properties be used in Transient RF model?

Please login with a confirmed email address before reporting spam

I have got a material whos dielectric constant varies along with frequency.

I would like to simulate a pulse fed into one port of my transient RF model.

The pulse frequency spectrum is broad. So, the dielectric constant should be related to the frequency. But I do not know how to define the dielectric properties dependent on the frequency. The eps(emw.freq) seems invalid.

Can I define frequency-dependent model in transient RF model? If so, how should I do?

Any discussion or answer is very appreciated. Thank you!
