Hello.

I want to use the sine wave for the input. Then, “continuous source"
was chosen and tried.
However, the result like the  sine wave cannot be obtained.

(define (my-output)
(print "sampled field:\t " (meep-time) "\t "
(get-field-point Ez (vector3 0 0)) "\n"))
    (set! geometry-lattice (make lattice (size 8 8 no-size)))

    (set! sources (list
                   (make source
                     (src (make continuous-src (frequency 1)))
                     (component Ez)
                     (center 0 0))))
    (set! pml-layers (list (make pml (thickness 1.0))))
    (set! resolution 10)
    (run-until 500
           (at-beginning output-epsilon)
           (at-every 1 my-output)
           (at-end output-efield-z))

Has it made a mistake in the selection of the input wave?
