Dear Shampy,
this topic has been discussed many times. Generally you can not force
a complex value of permittivity in FDTD. You can however define a
high-frequency oscillator that introduces losses.
More on this topic is at
http://ab-initio.mit.edu/wiki/index.php/Dielectric_materials_in_Meep
or search the mailing list.
I tried to make a list of some realistic material models at
http://fzu.cz/~dominecf/misc/eps/; the data used can be fed to MEEP.
Finally I would like to ask you to stick to the netiquette and write
your name as Shampy Mansha, not #SHAMPY MANSHA#. The capitals look
like shouting, and the hashmarks look like something as banging your
fist on the table before and after saying it...

Dear Steven and other Meep users,
I am doing a simulation in which I require to use a complex dielectric
constant of the form(say for example):
epsilon = 1 + 0.01i
For my simulation the frequency isn't fixed, instead I have to use a
gaussian source with some finite width.
And in the whole simulation I wish to use the same epsilon(epsilon =
1+0.01i).
Is there a way to do this kind of simulation?
Thanks,
Shampy Mansha
