I'll go back and try to find it. Sorry, "A bunch of IEEE PhD's" impresses me less than a handful of the guys posting here. Have you looked at the articles on the web pages I posted? Here's a funny quote, not previous quoted from: http://www.ttr.com/corum/index.htm "What frequency did you get in step 5? ... Is the difference within engineering accuracy ... less than 5%? If the answer is yes, then you may confidently use lumped-element modeling. However, if the answer is no, then, from the halls of Valhalla, old Wotan, himself, is thundering out over the battlements, '#*@&%!! ... Thor, you dumdum! You CAN'T use lumped circuit modeling!' ... [The coil has standing waves and is behaving as a distributed resonator.]" In case you missed it, here's what Walter Maxwell had to say about the subject: "If an inductance is in series with a line that has reflections, the current will NOT be the same at both ends of the inductor." "Consequently, circuit analysis will not work when both forward and reflected currents are present in a lumped circuit." -- 73, Cecil http://www.qsl.net/w5dxp |
