skin depth (eddy current/Foucault currentO)

Maxwell found his equations had the form of those predicting behavior of water waves and they correctly predicted the velocity of light as previously determined. This seems a distortion of the facts. The addition was seen as the forces between current and the force between static particles which was in fact a confirmation of the the speed of light. My understanding of the term eddy current with respect to waves was that it was ,made much later. But the realization of the connection to light should have really been recognised by Maxwell as a displacement of particles and not waves since the presence of particles is predetermined. This lack of understanding alsio helped the incorrect determination of light being a formation of waves instead of particles. This by the way also cements the validity of changing Gauss's law of statics to a dynamic field to equate with Maxwells laws which also confirms the presence of particles. Another correlation to my theory is the interaction of particles with the Earths magnetic field to produce Aurora or Northern Lights i.e. particles bombardmentnot waves, Same goes for light created at the center of a tornado which in itself is the "eddy current" of a storm where againb light is seen as a lightning strike where particles plus moisture is drawn into the stratoshere an d then become separated. The evidence just piles up that radio communication, radar and light itself is that which comes from particles ala Neutrinos and NOT from the formation of magnetic or electrical waves. And that Einstein was correct in his assertion that radiation held the key for the Universal laws of all the sciences of nature.Later when Foucalt discovered "Eddy current" which he associated with water eddy currents it then came into use as a non destructive material measurement system together with use in aluminum sorting in scrap yards which in essence is a macro demonstration of particle presence in radiation., again a vindication that the Maxwell addition was wrongly assumed a wave structure. I won't comment on your following statements as it is lost on me why you have quoted them and the point of stating them Maxwell was a mathematician and a physicist who searched for things with practical applications. In one of Maxwell`s lectures he said: "Now, Professor Graham Bell, the inventor of the telephone, is not an electrician who found out how to make a tin plate speak, but a speaker, who to gain his private ends, has become an electrician." Maxwell`s equations are adequate to solve all questions of radio waves at once in place of a multitude of their predecessors. Art even agrees they work as a basis for antenna programs in computers however he spells computer. Using the tried and proven until something better comes along is common sense. From what i`ve seen, wave theory works well for large scale predictions while the particle theory seems to work at the atomic scale. Too bad Cern had an instantaneous multimillion dollar breakdown. A.G. Bell produced the most valuable patent in history. What are the results of the Unwin patents? Best regards, Richard Harrison, KB5WZI * * |

Opposing ac current is total impedance, not just resistance. I tthink you have to go back to the beginning of this thread as again you are talking out of context. My statement referes to the current path on a fractional waqve antenna when it reaches the top. My point was that the current then procedes to the INSIDE of the radiator where the AC current cannot produce an eddy current and thus the opposition to current flow in the centre is just a copper loss i.e.resistance. This statement was made in requesting a possible different current path from the top of the radiator that provided a lower resistive path. I.E I pointed out that the impedance dropped linearly with respect to radiator length and thus I wanted a mathematically demonstrated different path that would counter my initial assertion. The deepest fibers in a conductor are encircled by the largest number magnetic flux linkages. These create a reactance which generates a counter-emf opposing an imposed current. The deeper the depth inside a conductor, the greater the opposition to the imposed current. I think I have stated what skin depth is and what created it many times so I won't respond to the above paragraph Look for "skin effect" in any edition of Terman and you will find diagrams illustrating the various magnetic flux paths inside the conductor which cause skin effect. I believe that the Wilkedia URL and Ian's supplied scanned page is adequate descriptions where the initial supplied current is the sum of the two currents in the circuit one of which is Maxwells determination of displacement current i.e.a current that displaces while providing an accelleration to PARTICLES (charges) from the surface of a radiator. If you can give an specific answer in mathematical form to the initial question asked it would be apreciated Other than that there is no need for continuation of this thread.

If RF current is flowing in a conductor - regardless of the reason - then the skin effect will be present. That is a very powerful conclusion. Because we know the skin effect will be present, it helps us to trace the RF current pathways on complex shapes such as coaxial cables and shielded loops. -- 73 from Ian GM3SEK * * * * 'In Practice' columnist for RadCom (RSGB)http://www.ifwtech.co.uk/g3sek Thank you very much for the addition supplied. I never really understood why hams could not accept this From my point oif view the beauty of the Foulcalt or eddy current is without this "pealing" on the chemical adhesion effect that a particle has on a diamagnetic surface the ejected particle would be without spin, and as such would not be able to have straight line projection within a gravitational field, a necessity for radiation. Any book on wave guides will picture this eddy current on the inside walls and any book on non destructive testing will also corroberate its presence and yet it is still rejected by this group. When Maxwell inserted the required units to achieve equilibrium per Newton it was the mathematics that forcast the presence of a levitation force that would not be identified for several decades but stil ignored because of the dominance of wave theory. Cheers Art I only just read this reply. NOTHING that I have said or referenced supports Art's ideas in any way. His ideas are totally deluded. -- 73 from Ian GM3SEK 'In Practice' columnist for RadCom (RSGB) http://www.ifwtech.co.uk/g3sek |

What you supplied with respect to skin effect was a coroberation of the Wilkpedia definition which I stated WAS correct also in the face of a statement that said otherwise. And I thanked you for supplying it and no more. You may call me delusional as a sample of free speech but you like the others have never supplied an iota of evidence that shows that my ideas have zero merit and thus are indulging in childish attacks. I know that you posses the AO antenna computer program and feel very comfortable with the fact that you are capable of putting in a one liner that shows that a radiator for maximum efficiency will be devoid of parallelism. Unless you initially guide a antenna optimiser towards a planar design the program will respond with a non planar design That is a fact and is not delusional. Statements like that is no more than support for the many talking heads. This is a ideal place to point out once and for all a basic fact that points to the feasability of my analysis.To deny or try to cover up this computor fact with respect to the avoidance of a planar design because of the addition to general laws by Maxwell is understandable by those who do not have the means to challenge the books is understandable but for you there is absolutely no excuse and shows a dependence on emotion while at the same time pushing aside scientific fact a fact that that is undeniable. A planar design is a approximation with respect to Maxwells laws. A antenna omptimisation, if allowed, will always respond with a NON planar design to conform with all aspects provided by Maxwell's laws which I might add includes the addition iof the "weak" force as suspected by Einstein.
