Good night:

Is there any way to modify the Electric displacement model manually? I am using the RF Module to analyze periodic structures, however, according to the literature, the relative permissiveness is obtained through the equation εr = (n - ik) ² + 2nik, the latter term not appearing in COMSOL and I would like to insert.

I'm not sure I understand the question. You can insert a complex relative permittivity for any material.

I managed to understand. In fact, I had a doubt because the other term didn't appear. In fact, it is already inserted, I made the mistake. Thank you, Dave.
