Sounds like you're talking about Scott Roleson's technique. It works for mechanical resonances (cavity res. and the like) too: anything that amplifies a particular frequency or band. I've seen it demonstrated but I can't come up with a written reference either.

I think the author was working at H-P when he wrote the article. Sorry I can't remember where the article was published.
