Dear All,

Hope you're doing great. I'm trying to simulation solar radiation in 3d
[200nm to 1200nm]. But the problem is, if I define a broadband source
covering the whole spectrum, intensities for lambda<300nm and lambda>400nm
are really small, i guess for that reason I'm getting weird results in the
simulation. Can anyone please direct me how to define a broadband 3D plane
wave which covers the whole spectrum uniformly?

Thanks,
Yasser

; lambda = 200nm ---- 1200nm
; u = 0.083333 ---- 0.5
; delta u = 0.4167
; ucentral = 0.29166
(define-param fcen 0.29166)
(define-param df 0.4166)

(set! sources
    (list
    (make source
    (src (make gaussian-src (frequency fcen) (fwidth df)))
    (component Ey)(center 0 -2)(size sxy 0))))
