Hallo Steve and everybody,
At first, I want to thank you all the help you are offering in the
meep-discuss mailing-list.
My problem is that I have the following structure with different dielectric
materials with dispersion and
I want to calculate the absorption (the loss) only in the Germanium(Ge)
layer, but I am not sure how.
Source is placed in the first Air-layer(1) and the simulation is run in 2D
(propagation direction is x)

I tried to calculate the loss coefficient with the help of flux areas
(lines) just before the Ge-layer and just after the Ge-layer.
But the results are not the expected, because the transmission coefficient
is greater than 1. (not logical)
I do not know how to deploy this measure, because in the example of the
tutorial "Transmission spectrum around a waveguide bend"
there is one first simulation without dielectric and another one with
dielectric.
In my case with many dielectric-layers, it is possible to calculate the loss
with the flux areas? How should be the first simulation?
And if not, how could I calculate the absorption or loss of this layers?
Thank you in advance.
Best regards,
Mario Cao
PS: Sorry if my english is not very clear.
