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
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.
