I want to set epsilon diag and offdiag vectors. Can it be done by using
epsilon-func? Or do I have to use material func?? Please help!
Here is my code:
(define myeps
(lambda (p)
(sqr (+ (* (- nglass nair) (sqr (sin (* 2 (vector3-y p) (vector3-x
p))))) nair))
))
(set! geometry-lattice (make lattice (size 5 5 no-size)))
(set! geometry (list
(make cylinder (radius 2) (center 0 0 0) (height infinity)
(material (make material-function (epsilon-func myeps))))))
