good night all Meep users.
My second problem s about ascending geometric-object-duplicates command . I
try to define photonic crystal 2 D, and I try to duplicate a cylinder in 2
directions, x and y. I use this code
(set! geometry
(append
(geometric-objects-duplicates (vector3 0 0 1) 0 5
(list
(geometric-objects-duplicates (vector3 1 0 0) 0 50
(list
(make cylinder (center 0 5 0)
(radius 0.35) (height 6) (axis 0 1 0)
(material silicon))))
(geometric-objects-duplicates (vector3 -1 0 0) 0 50
(list
(make cylinder (center 0 5 0)
(radius 0.35) (height 6) (axis 0 1 0)
(material silicon))))))))
Meep shows error message
ERROR: In procedure vector->list:
ERROR: Wrong type argument in position 1 (expecting VECTORP): #f
for fullfiling my purpose, what code do I have to write?
Thank you so much for the answer.
with regard
Andika Asyuda
