Hi,
I'd like to do some eigenfrequency calculations with meep.
For testing purpose I've written a simple ctl-file,
and defined an example source as:
---------------------------------------------
(define (own_source r)
(exp (* 0+2.0i pi (vector3* r k-point)))
)
(set! sources (list
(make source
(src (make gaussian-src (frequency 0.7) (fwidth 1.5)))
(component Hz)
(center 0 0 0)
(size 1 1 1)
(amp-func own_source))
))
(set-param! k-point (vector3 0.0 0 0))
(set! force-complex-fields? #t)
(set! resolution 20)
(set! eps-averaging? #t)
(run-k-point 300 (vector3 0 0 0))
-------------------------------------------------
If the component is Hz, no frequency could be found,
but if the component is Ez harminv finds some.
When I look in meep.scm, I find that the function run-k-point seems to seek
for the correct field-component in the source(s) and gives the parameter to
harminv.
So where is my mistake?
kindly regards
Andreas
