Yes, you can do this. Meep has a subclass of sources called
"custom-src", (see the meep reference).
(define start 0)
(define end 300)
(define mysource (lambda (t) (sin (* 10 t))))
(define cs (list (make source
(src (make custom-src
(src-func mysource) (start-time start) (end-time
end)))
(component Ez) (center 0 0) (size 0 0))))
(set! sources cs)
You will need to write a function in scheme that to replace "mysource",
which when passed a time argument, will return the value of source
amplitude you desire. I guess you want that function to interpolate
between sampled data points, which you could store in a list or import
from a data file.
