Dear MEEP users,
I wanted to define a structure using nested loops (map function).
Here is the code :
*********************************
(define structure
(map(lambda (i)
(map (lambda(j)
(make sphere (center i j (+ i j) ) (radius r) (material dielectric) )
)(arith-sequence 0 dx 10)
)
)
(arith-sequence 0 dx 10)
)
)
(set! geometry (append
structure
))
***********************************
but I get this error:
wrong type argument in position 2:0
How can I solve this problem?
Thanks in advance,
Ehsan
