Dear colleague:
The example of the transmission spectrum in the tutorial,I want a
loop for different index.
Like the following:
(do ((n 2.7 (+ n 6e-3))) ((> n 2.8))
(set! geometry
(list ............))
(define trans ; transmitted
flux
(add-flux fcen df nfreq
(make flux-region
(center wvg-xcen (- (/ sy 2) 1.5)) (size (* w 2) 0))))
run-sources+
(stop-when-fields-decayed 50 Ex
(vector3 (/ (+ w space) -2) (- 2 (/ sy 2) ))
1e-3)
)
(display-fluxes )
it is wrong,because of the define,But the add-flux have to be after the set
geometry.
How should I do? Thanks
