Dear Dr. Johnson and meep users,
I am very new to meep. I'm trying to simulate a 3d structure (a rectangular
block) but the following error appears:
ERROR: In procedure vector-ref:
ERROR: Wrong type argument in position 1: #f
Charalampos Mavidis
The ctl file:
(define-param polym_th 4) ; thickness of block (100*1nm)
(define-param eps_r6g 2.56) ;
(define-param s 6) ; size
; OTHER PARAMETERS
(define-param dpml 1) ; PML thickness
; #############################################################
; GEOMETRY
(set! geometry-lattice (make lattice (size s s 18)))
(set! geometry
(make block (center 0 0 0) (size s s polym_th)
(material (make dielectric (epsilon eps_r6g)))))

)
(define trans ; transmitted flux
(add-flux fcen df nfreq
(make flux-region
(center 0 0 -7) (size 6 6 0) )))
; display the flux
