Stainless steel is a lousy RF conductor, especially if it's a magnetic
alloy. It can also be fairly tough stuff to work with. It might be
usable in a flat plate or extended foil design. I'd recommend using
aluminum foil - it's inexpensive, readily available, and almost as good
a conductor as copper.
