You should only be able to activate the SPP for TM polarization..
Which appears to indeed be what you are observing! --Judson

Not sure.. But this could happen if your field is building up to be very
strong near the very end. The -R option should normalize it to the max/min
for all related datafiles, which could make the field look very weak in the
beginning? Try just using -Zc to see what happens, or consider setting
Yes, I've done a bit of this.
Matlab has a built in command, hdf5read(). Before you use it however, you
need to know more about the size and handle of your dataset. So in the
terminal where you run meep, use the command *h5ls filename.h5. *This will
give you the dimensions and handle of the

.
Just remember to only define the PML on the x direction, and use k-points as
shown.
Good luck!

Hi all,
I have tried to define a custom field function to take the average dpwr
and divide it by epsilon and output that to a .h5 file. However I keep
getting an error meep: unknown field component 105. Note below,
everything runs smoothly if I stick to using non-derived components (i.e.
Ey, Hz,
was that for some
simulations, using an invalid k-point and omega lead to a time varying dpwr.
This could be fixed by rerunning the bands calculation and then using the
appropriate k-value...
However, if anybody has any other insight, I welcome discussion.

Hi all,
I've got a question that could be simple to answer, even though it has been
bugging me for several hours.
Let's suppose you run a k-point simulation using Bloch-periodic boundary
conditions, just as in the holey waveguide tutorial. (i.e. we specify a
kx=value1, fcen=value2). In the
I think you should probably change your scale. i.e. Make the sphere radius
equal to 1 in meep units, and define that (for yourself) as ten nanometers.
Then you just need to scale the frequency of your source equivalently.
Goodluck!

Can't you just make a normal transmission and reflection spectrum of your
structure, and then multiply by the shape of the desired input spectrum?
Good luck!

Steffen,
I would recommend using MATLAB to perform mathematical operations on your
h5-files (if you have it). You can load each file into matlab using
something like
ep = hdf5read('epsilon.h5', 'data')

Dear Steven,
I have been using meep recently for simulating a metallic grating in
2D. As most people have discovered, simulating metals in meep can be
rather tricky if you don't do it correctly. Thanks to your tutorials
and discussion threads I have managed to make good progress. While I
