guided band in the bandgap. So i want to have a look at the H field
of the
band24, 25. here i got a problem, i cant make MPB to put out the H
field
at a k point of (0.1 0 0) (reciprocal). what i can get is the H
field at k
point (0.5 0 0). Is that MPB can only output the field at edge of the
Brillouin zone? or something i have done wrong?
I ran your ctl file and it outputted at k=0.1 as you specified, and
the fields look okay to me. Maybe you are just misinterpreting the
results? I would recommend using mpb-data to expand to more than one
unit cell in the x direction when you visualize, as it is a bit hard
to see what k point you are at if you only look at one period. e.g. I
used:
mpb-data -x 10 dudu-*.h5
h5topng -Zc bluered -C dudu-epsilon.h5:data-new -d z.r-new dudu-
h.k02.b*.z.te.h5
and got the attached image for the guided mode of band 25, which
clearly has period 10 as you would expect for k=0.1. (I reduced the
resolution to 10 so that it would run faster.)
