I want to thank you for all of your help thus far in addressing the issues I have encountered in my FDTD simulations, ma’am. I have done what you recommended: changed the material of the plates from aluminum to PEC, changed the profile to “steep angle” in the boundary conditions tab (I chose 24 layers - double the default value of 12), and enabled monitor apodization to “start” with the center time of this apodization setting to 2 ns and the time width to 1 ns. I am concerned whether or not I have correctly implemented the monitor apodization here.
I was also wondering how to utilize the Q factor analysis specific to my simulation. I have seen the scripts provided in the example .fsp files in the link you provided, but cannot get any results when I attempt to run the script within my file. Essentially, I am trying to reproduce the plots shown in Figures 2A and 2B in the attached paper below, particularly Figure 2B which shows transmitted power (in dB) as a function of frequency.
I feel that I am close to getting these exact, or very similar, results shown in the two aforementioned figures from this paper. I am seeking to make sure my settings are indeed correct for obtaining those results, but have hit a wall
I have attached my updated simulation file and reference paper whose results I am attempting to recreate below.
