I thank Michele for his comments and agree with his proposition that "scientific discussions are always useful." But this is only true if all parties enter into the discussion with an open mind regarding alternate points of view. <><><><> In this regard, I am a bit puzzled to learn that Michele appears to believe more in "mathematically sound deductions than in my own perception of the phenomenon." It almost sounds as though Michele ranks mathematical precision as being more important than reality. That is a proposition I cannot support. <><><><> I have NOT proposed that Displacement Current does not exist AND that Maxwell equations are correct. A review of my paper will show NO MENTION of my opinion regarding the veracity of Maxwell's equations. I only mentioned his name to provide a historical context. <><><><> However, I will point out that transmission lines have been happily carrying electromagnetic waves (without benefit of displacement current) since "WHAT HATH GOD WROUGHT" was tapped out in code over a century ago. I will leave to other, more mathematically erudite individuals to determine what -- if any -- effect the absence of displacement current may have on Maxwell's equations. <><><><> After a brief attack at my unabridged dictionary -- in a hopeless search for "fenditure" -- I found the Synatx Error posting and now understand that Michele was referring to slot/window/aperature antennas. :-) I have quickly reviewed my various references to this class of antenna. Since I am suffering from "Saturday morning syndrome," I'm afraid I have not been able to locate any reference stating that any member of this class of antenna DEPENDS on or USES displacement current. All analyses that I have seen appear to rely on plain old garden variety antenna designs.<><><><> Thus, IMNTBHO I have not yet seen anything that negates my proposition. Displacement Current is a delightful myth. reGARDS to all, Bill KT4YE
