Dear Steven and meep users.
I have been conducting some simulations by meep, and I have a question about
frequency in meep.
In meep reference page, it is said that the frequency in meep is ω and it is
normalized by 2πc/distance. From this script, I think that the frequency in
meep is angular frequency which is 2*pi*freq (freq is a real frequency, not
frequency in meep). Is it right that the frequency in meep is angular frequency?
In this case, in "Materials in Meep
(http://ab-initio.mit.edu/wiki/index.php/Materials_in_Meep)", it says that I
have to set a sigma_d as (2*pi*0.42)*0.101/3.4 in order to use a medium with
eps=3.4+j0.101 at a frequency 0.42. However, if the frequncy in meep is an
angular frequency, I think that the term (2*pi) has to be effaced because the
frequency in meep is already an angular frequency.
It is a very important problem for my simulation. I'll appreciate you if you
answer my question.
Thank you.
