[Meep-discuss] How to create position dependent epsilon function?

[ps13ms039]

I want to define epsilon as a function of position.

Here is the code:

(define (myfunc p)
        (vector3 1 1 1)
)
(define mat
        (make material-function
                (epsilon-func myfunc)
))
(set! geometry
   (list
      (make cylinder
        (material mat)
        (center 0 0) (radius 2)(height infinity))
))

Please help with an example or same.
