could work it out by using a complex
permittivity, but it seems meep doesn't appreciate complex values for
this. Furthermore, a perfect conductor appears not to give the
required phase shift I need.
Any suggestions would be greatly appreciated.

the phase have any meaning in this case
either?
Other commercial FDTD codes have this feature, so I assume that
there's a straightforward way to accomplish it. Any ideas or examples
are greatly appreciated.

reflections from this thin piece of glass cause all sorts of
interference, ruining my afternoon.
So, how would you simulate such a system?

of dielectric was simulated and was exported with the command
meep-fields-analytic-chi1, and then compared with LD.m
There's also fused silica, which matches quite well what you obtain from
the Sellmeier equation.

, it's
probably good enough to use the permittivity at a single wavelength. Of
course,
make sure that the theoretical value is the one meep is using.

You could try, but numerical instabilities are unavoidable in FDTD
simulations. If you have to solve for some steady state behavior where
energy is building up, frequency domain methods might be a better option.
