Hello, Michele and thanks for continuing the discussion. <><><><> Rather than re-iterate (again) I hope you will take the time to review the postings I made to David and Alan. In a slightly different way, they were asking the same questions that you raised. <><><> Having corresponded with David and Alan for several years, I can assure you that you are in good company! <><><> I'm intrigued by the implied assertion that the existence of Displacement Current can be proven mathematically for transmission lines. Since your PhD is in mathematics, I will not be so impudent as to question your assertion. However, I have looked at many different "proofs" of the existence of Displacement Current. Without exception, every one that I have been able to find follows the general outline of the proof (by Alan) that I cited in my article. At the end, they all state words to the effect of, "Since we have proven that Displacement Current exists for this structure, by extension it exists for all structures." <><><><> You and I have already agreed that the E field in a capacitor cannot be uniform, since the field can travel no faster than the speed of light in the medium. This is a key flaw in proofs like the one i cite in my article. <><><> I wonder if you would be kind enough to review your literature and/or past research and direct us to a more comprehensive proof of displacement current that A) Takes into account the non-uniformity of the E field in a capacitor/transmission line, and B) Demonstrates that Displacement Current exists in a transmission line? <><><><> I know that such a proof will involve the us of mathematical operations, but ANTENNEX's publisher, Jack Stone, has already demonstrated his willingness "to go the extra KM" to provide a forum for this type of discussion. <><><> At the risk of getting Jack mad at me (again) I'd bet he would be happy to provide E-space for such information. <><><> All the best.
