Dear Prof. Steven and meep users!
I would like to ask you about the Amplitude in (run-k-points ...) simulation.
What I want to say...
If I do the simulation of light propagation in 2D structure (planar dielectric
waveguide) with the cw source,
I set the amplitude A, for example, and I can obtai
Dear Peng,
have you tried to start meep not from matlab environment but from ubuntu's
shell which you prefer to use?
And have you installed meep from debian's repository or compiled it by
yourself?
BR,
Alexandr.

Dear Liu,
I suppose you can consider the nonlinearity as
a some addition intermediate step in FDTD algorithm.
So the amplitude of signal does'n affect the epsilon tensor (or epsilon value),
just when we compute D field from E field (maybe vice-versa, E from D, I don't
know exactly),
we use so
dear, David,
maybe there aren't symmetrical TM modes in your geometry.

Brian, what does the start-up pulse mean?
Maybe you shoud increase your computational time
in order to skip the transient process.
Try to explain your problem more detailed in other case.

nonlinear Shroedinger equations.

Dear Matti, I suppose you can use the exmples from meep tutorial pages,
and you have to carefully read about PML conception in meep, if you
did'n do any similar computation with FDTD formerly, because the simulation
of the antennas system is the simulation of open system I suppose.

Now I'm trying to set the specific material type using
meep ctl interface (not C++).
I consider the carbon tube, which has the different

axis.

First of all I would like to thank Dr. Paul Kinsler for answer on my previous

Thank you, Matthew, for the answer to my question.
I've studied you letter in which you answered to Jian,
but for my problem it is not a solution.
