Hello, David... And welcome to the fray!<><><><> You are quite right in everything you said in the posting above. That's why I concluded my article by stating, "The 'classicl' model (of the capacitor) is perfectly OK for essentially all engineering designs." <><><> See! I agreed with you and said so! <><><><> In virtually all engineering designs, the capacitor is an ENCLOSED device, whose characteristics are well known through (external) measurements. As long as the device works reliably, we could not care less whether the current passes from one side to the other by means of Displacement Current, TEM waves, or by transmogrification of aetherial non-conductivity parameters. <><><><><> (I would like to suggest that this fact is one of the primary reasons why Mr. Ivor Catt's earlier concepts were so roundly ignored. Frankly, nobody cared!) <><><><> But this is ANTENNEX, and we are supposed to be talking about antennas. In some of the most controversial antenna designs, (CFA, EH etc.) the designers are not dealing with a contained device. Instead, they are attempting to "open up" the capacitor and USE its (supposed) internal workings in an external environment. It is in this context that the flaws in the "classical" capacitor model manifest themselves. <><><> 73, Bill KT4YE
