Thank you very much for your reply. However, perhaps I should explain my question better.
I was working on using a Gaussian pulse as a source. I used a Gaussian font with a very short df, but there were still a lot of resonances. Then I thought of a continuous wave, so there would be only one frequency for analysis. But then the unwanted frequencies produced by the nature of the continuous wave appear. I didn't know what to do. If someone has already simulated material with PT symmetry and can provide some help, it would be wonderful. ---------- Forwarded message --------- De: Patrick Flanigan <flani...@etaphase.com> Date: seg., 19 de out. de 2020 às 01:54 Subject: Re: [Meep-discuss] pt symmetry To: Cícero Julião <juliaojun...@gmail.com> Cc: <meep-discuss@ab-initio.mit.edu> This might help: https://meep.readthedocs.io/en/latest/Materials/#conductivity-and-complex On Sun, Oct 18, 2020 at 12:23 PM Cícero Julião <juliaojun...@gmail.com> wrote: > Dear friends, > > I'm trying to write a code to simulate material with PT symmetry.
