I think someone would be in a lot of trouble if you find the recipe for
a specific stealth aircraft on the Internet. The "spacecloth" mentioned
in another post could be similar to Echosorb, a popular microwave RF
absorbent material that is available in sheet form. It ranges from a
1/16" thick pliable rubber to thicker, multilayer foam that looks like
the black antistatic foam used to ship IC's and other semiconductors.
