Hi, Steven and other MEEP users,

I tried to do


;--------------------
(set! dimensions CYLINDRICAL)
(set-param! m 1)
(set! geometry-lattice (make lattice
    (size 5 no-size 5)))
(define Si (make dielectric (index 3.45)))

(set! geometry (list
    (make cylinder (center 1.5 0 0) (radius 0.5)
       (height infinity) (axis 0 1 0) (material Si))))
;---------------------


 with component Hp. The output-epsilon file shows something so

         _______
        |      O     |
        |             |
        |             |
        |_______ |


 What is this? It is a toroid with principal diameter 3 and minor diameter 1
?

If it is not a toroid, how can I do it in CYLINDRICAL coordinates?

Many thanks!
