Dear MEEP's users
After making the structure of PC slab with point defect cavity in the
center (only change the dielectric constant of the point defect cavity). I want
to study high-Q (long lifetime) resonant modes by using some MEEP commands:
(set! sources (list
(make source
(src (make gaussian-src (frequency fcen) (fwidth df)))
(component Hz) (center 0 0 0))))
(set! symmetries
(list (make mirror-sym (direction Z) (phase -1))
(make mirror-sym (direction Y) (phase -1))
(make mirror-sym (direction X) (phase -1))
))
(run-sources+ 300
(at-beginning output-epsilon)
(after-sources (harminv Hz (vector3 0 0 0) fcen df)))
(run-until (/ 1 fcen) (at-every (/ 1 fcen 20) output-hfield-z))
Where: fcen is the center frequency, and df is the width of the gap.
I don't understand why my results are not correct? Please, help me!
Thank you,
Sung Park Lee
