;Here is one way to define a Gaussian beam profile in a 2D model.
;Define gaussian amplitude function
(define-param sigma1 1.0)
(define (gaussy y)
(exp
(* -1.0 (/ (* (vector3-y y) (vector3-y y)) (* sigma1 sigma1)))
)
)
;This example is for a pulsed source
(begin
(set! sources (list
(make source
(src (make gaussian-src (frequency fcen) (fwidth df)))
(component Ey)
(amp-func gaussy)
(center (+ dpml (* -0.5 sx)) 0)
(size 0 w))))

How can i define a Gaussian beam profile?
I have a waveguide and i want to a have a Gaussian profile in the end.
