Yes. There's a development of this concept on my website, where the 
matching method is used as an example in a tutorial on using SimSmith to 
design antenna matching networks.

When I was introduced to the concept by local contesters, they credited 
it to Dave Leeson, W6NL. When asked about it, he said the idea was much 
older than he was.
