A couple of things to consider. The z coordinate of your volume seems to
lie outside of the computational cell. Also, it seems that you are
outputting the fields at every point in the computational cell (since
the z size of the volume is "sz") whereas you may want to output the
fields at a single point outside the slab.
Another way to output the fields as a function of time is to use a
custom step function, as follows:
(define print-field (lambda()
(print "ex:, " (meep-time) ", " (get-field-point Ex
(vector3 0 0 (- (* 0.5 sz) dpml))))))
(run-sources+ 1600 (at-every 0.3 print-field))
This will print the results to standard output which you can use for
post processing.
