One of the reasons for seeing a pulse multiple times could be
reflections. In your case, your PML is 2 cells wide (thickness is 0.1 at
resolution of 20). How about making your PML thickness 1.0 instead?
Your pulse could be bouncing back and forth between the two Y walls
inside your dielectric.
Hi Francisco,
car and cdr are list-access/manipulation functions in
Lisp/Scheme, if I remember my functional programming correctly. Try
looking up references related to these to understand the error messages.

Hi all,
Meep's polarizabilities are specified using omega, gamma,
delta-epsilon, sigma etc. Should the gamma be specified in units of c/a
or 2PI*c/a?
This doubt stems from the Johnson and Christy paper on optical
constants for noble metals where gamma is specified as 1/tau where tau

Hi Dr. Johnson and other MEEP/FDTD knowledgeables,
I was thinking about why MEEP should allow only a real dielectric
constant. In the monochromatic case it would make sense to evaluate the
dielectric function at the frequency-of-interest \omega_0 and plug that
into Maxwell's equations,
I'm in the process of decrypting MEEP's C++ part. what I dig up I add to
the C++ reference wiki page.
MEEP's interface with libctl is in the libctl/ subdir, not in the src/
subdir. Also, some of the header files are generated from basic
specifications in the hsrc/ subdir using Haskell (ghc).
Objects such as blocks, cylinders, cones etc. are geometric objects.
Look up the MEEP libctl reference for a list of allowed types.
A collection and arrangement of these in your simulation volume is the
scene. You will find the term scene used in a similar manner in
computer graphics (and

Look at the documentation for CFLAGS, CPPFLAGS, CXXFLAGS, LDFLAGS. You
might just need to set CPPFLAGS and LDFLAGS but if that doesn't work try
setting the others too to point to the structure inside your home dir.
On the gcc command line
search the dirs you specified first before looking
up the standard dirs.

This should work. This will only spit out libmeep.a and no meep
executable in the libctl/ subdir.
cheers!

If you have super-user access to your machine then installing
guile-devel, libctl and libctl-devel will correct dependency issues.
Using the MEEP libctl front-end is great for prototyping your program.
If you want to bypass these because of issues with configure then try to

Hi Dr. Johnson,

polarization would then be the state of the material with the given
polarizability and under the influence of the sources at a particular

may be enough. But if we do this would it be able to handle obliquely
oriented line and plane sources?

Regarding the flux-in-box function, it needs a direction, and a
box-shaped volume. I don't clearly understand this. The example in the
