Electromagnetic Waves in frequency domain, with time-dependent parameters

Please login with a confirmed email address before reporting spam

Hello,

I need to solve an electromagnetic wave problem in the frequency domain, coupled with a time-domain thermal problem. In particular, I have to determine the S11 at a coaxial port as a function of time, with the dielectric constant of the material filling the line changing with time as a consequence of the temperature variation.

With version 3.5 that was very simple, but now I obtain a "warning sign" in the Time Dependent section of the Study (on the line corresponding to the "Electromagnetic Waves" physics) and the S11 results 0 for every time.

Any suggestion?

Roberto
