At 10ghz, almost anything becomes a reflector, no?  Otherwise,
RADAR and those automatic door openers would never work.  But,
you can't get good performance from a dish made from a wooden
salad bowl.  I think we need a more quantitative test than the
one you did to know if it would really make a good reflector.
(I suppose one way to find out is to build one...)

Ah! Finally a good use for all those AOL CD's...  A 1.2 ghz disk
