Hello all,
this is probably something relatively simple but I am having trouble including
multiple field components in the plot2D method and animate2D class (for example
including both mp.Ex and mp.Ey). Is there a simple way to set this up through
the user interface?
Thank you very much

p.s the colormap error might have been due to a problem with a sub process call
instead of with h5utils itself.

the scaling transformation running.

I am not sure what you are working on but depending on your structure maybe an
FEM solver would be more suitable (could be true for my case too). Sadly I am

Dear all,
I was wondering if anyone has experience with using the coordinate transform
with nonlinear materials (materials with chi3 etc).

Thank you very much for the reply. I will try to implement it this way and will
provide updates if successful.

You have to modify the math to handle nonlinear materials in transformation
trying to
simulate 3rd harmonic generation in graphene for example.
This is going to make things a bit challenging.

Thank you very much for the reply. So I should, for example, use the Drude
model to fit the graphene conductivity over the desired frequency range and
follow the tip from FAQ and assign it in the form of an anisotropic volumetric
conductivity (or permittivity) to a block with a 1/resolution
Dear all,
Since mp.get_fluxes() gives the Poynting flux due to all field components, I
was wondering if there is a smart way to obtain the Poynting flux through a
monitor region separately for Ex and Ey, as well as the phase associated with
them.
Thank you for your time.

Thank you very much, I see it is well documented in the user interface page.

Dear Prof. Johnson and MEEP users,
I have been playing around with the Cherenkov radiation example with the goal
of monitoring the fields generated due to the interaction of the moving charge
with a geometry (cathodoluminescence, transition radiation, scattered fields).
I also aim to obtain
Dear all and Prof. Johnson,
I have written a code that studies the polarization dependent scattering
properties of a plasmonic nanodisks. As a test material I used gold from the
material library included with Meep and everything works well. For the actual
simulation that I am interested in I
Dear all,
I am new to MEEP and I am trying to simulate a gold plasmonic scatterer.
I am specifically interested in utilizing a 45degrees polarized source (between
x and y polarization) or a circularly polarized source in order to excite the
plasmonic nanoparticle. What would be the most
Dear all,
I have seen that it is possible to input a dispersive complex permittivity for
a material by using for example DrudeSusceptibility or
LorentzianSusceptibility. Is it possible to do the same for conductivity models
such as the ones that are commonly used for 2D materials? I am also
