I am simulating a very simple scatterer exposed to a plane wave. This is a
metal strip with length equal to lambda/2. It is my understanding that this
should behave like a half-wave dipole. To check the response, I'd like to
estimate the current in the conductor - I think this should have a
I'm not a real programmer either, and I don't know what the function is
doing, but I think I can make sense of the way p and p_prev are incremented. p
is initialised to d-data, and p_prev to d-data + ntot, i.e. a memory address
ntot*sizeof(realnum) past p. This is because when a
Look at the tutorial examples. The command (display-fluxes trans refl) writes
out the flux spectra.

Indeed the ramp works well - see the attached pic. This used
width=2*wavelength, and the simulation was for 20 periods.

I have been running meep-mpi (latest code) on our cluster, using output-png.
All has been going well, but now a couple of runs show an odd problem. Looking
at the output directory I see the expected sequence of .png files, but then
there is a .h5 file as well as the corresponding .png file.
Hi Steve,
I am a beginner with Meep, but I have seen posts with various recommendations.
One recommendation is that the flux plane (in 3D) should be located at least
one wavelength from the scatterer, and also from the wave source. The PML
should be at least one wavelength thick, and the
I don't think you were confused, but I'm wondering where I should get the fixed
code from.
Is this it? git clone https://github.com/stevengj/meep

I am trying to characterize the reflection spectrum of a simple metal
