Hllo, Michele and thanks for your insightful comments. <><><> You are correct in that Mr. Catt was one of the earliest researchers to realize that Displacement Current was a myth. <><><> I'm sorry you don't have access to the second half of the article. Perhaps one of the subscribers -- with your Email address -- can send you a copy of section 2. <><><> When you receive it, you will note that one of the references that I cite is, in fact, Mr. Catt. <><><><><> When you read the second half, you may -- perhaps -- concur with Alan that the difference between a transmission line and a capacitor is a matter of scale. If so, I pose the following question: Let us postulate a "large" (but less than 1/4 wavelength) Open Circuit transmission line that -- as we all seem to agree -- does not employ Displacement Current, and a "small" one that REQUIRES it.<><><> As we shrink the "large" line towards the "small" one, at what point, and by what mechanism, does Displacement Current appear? Is there some "critical dimension" or "critical ratio" wherein Displacement Current suddenly "snaps" into existence? Or does it slowly emerge from the aether, gathering form and substance until, like a cayman emerging from the swamp, it achieves reality?<><><> Or can we finally admit, as I believe we have demonstrated, that Displacemet Current does not exist?<><><> All the best.<><><> Bill KT4YE
