Hi all,
I have a following problem, and any clues are much appreciated.
I want to do a simple 1D simulation of normal reflectance from air to a
dielectric of constant epsilon (eps=9). According to Fresnel's equations
reflectance should be 0.25 regardless of frequency.
But, when I send a Gaussia
Dear Hessam
It is nice work, thanks a lot.

Dear Mahdiyeh
I have your problem in dispersive and constant dielectric functions and
actually i have found that it is "numerical dispersion" and it's common problem
in FDTD method. you can find it in many papers and books (you need just
Googling). Best way I have found to decrease the effect
Following on my previous mail, a note to clarify:
I meant, something that allows _not_ to pass through the 'eps' file, i.e.
extracting to GDSII only the vertices of the blocks or something similar.
As you might know, GDS doesn't handle well large vertex counts, and extra
feature complexity might
Hi Serge,
Yes it is possible, just use the second formula in my email...
I don't think integrating in MEEP is necessary... I'm not sure, but I think
output-dpwr already gives you the average power, IF you use complex fields
The following thread seems to confirm this:

Hi Serge,
I'm working on a similar problem, I have a resonant cavity...
What I do is, I excite the cavity with a pulse and wait for the fields to
settle down.
As soon as the fields have settled down, I know extract Q factor of my cavity
plus the |E|^2 field distribution.

Dear all MEEP users,
is anyone aware of a method to convert HDF5 dielectric layouts (the 'eps' file)
into GDSII, without pixelization?
I am asking because my design involves features not parallel to the axes.
Thank you and kindest regards,

Hi everybody,
I'd like to output the electric field intensity (|E|^2) from a 3D simulation.
I wrote the following function:
(define (eSquared r ex ey ez)
(+ (* (magnitude ex) (magnitude ex)) (* (magnitude ey) (magnitude ey)) (*
(magnitude ez) (magnitude ez
(define (output-efield2) (outpu
Dear MEEP users and Dr. Johnson,
I'm trying to calculate absorption in the device. I start simulation with CW
source, wait for a while... this is OK.
Then I output electric-field energy density using (output-dpwr). Using
average energy I can calculate the absorption.
But as far as I understood I
