I recently gave a write up on Gaussian arrays
As a sample which was not directed for any desirable I laid out the following All of the elements were placed above each other purely to make things easier to do plus it being an unusual arrangement probably never seen before. Coordinates ( perfect ground) Inches X Y Z 0 209.46 927.1 0 198.25 973.97 0 172.78 822.86 0 219.83 964.4 0 185.53 922.4 With 1" dia elements my results were Impedance 48.5 + j 0.1 Horiz gain 8.12 dbi @ 12 deg Rc gain 5.11 dbic Since I am not sure of the capabilities of EZNEC or other programs I also supply the following All elements driven impedances are 6.58 + j56.9 -5.28 - j 37.6 -5.00 -125 9.35 + 58.5 -16.2 - j205 Now I need the help from anybody with a engineering degree which wipes out Richard since his only intent is to ridicule, or deceive anyway, to confirm the following For a Gaussian field the energy radiated by the array as a whole ( feed element 1 ) must equal the sum of the energy supplied from each individual element. Questions. 1. Am I correct in saying this? 2. Does the above array rank in any way as a Gaussian array.? Frankly, one or more of you is an academic so I really am pointing at you for direction so I can be sure that my program has not somehow become corrupted I am sharing this with you so can you share your input with me? If you prefer to communicate by E mail with me that is fine since we know that the lips of some will spew Art |

David listen to me. Please. Gaussian law with respect to electrostatics
is very well known And you surely are aware that electrostatics is a subset of electromagnetics. Now you, because of your education and professional experience know that the energy radiated can be calculated tho it is laborious to do. I have given you a Gaussian version where only V=IZ needs to be known where as other means require coupling factors plus other things. Gausses law is very simple, the energy provided by the addition of curl to the contained static electrical particles is equal to the radiation outside the arbitary border when you add " in a space of time" or something similar to Gausses law. Yes it is not in the books because it is new, thats right, new in my eyes because it provides an array without the addition of elements that are detuned as with the Yagi. With the Gaussian array you do not have to make compromises with respect to desirables as shown in Chaptor 2 in the Antenna handbook. The Gaussian array provides sync between all the curves over a bandwidth. Over time I have written this patent application many times because of derision from amateures. But, now I am appealing to the academics or qualified engineers. (I once was an engineer but time has messed the mind in some areas}to help me out so I can finalise things but above all I want academic facts and not drivel that I get from those who follow Richard. Is there any other academics out there that can help me out as well as clarifying what I say for better understanding. Anybody to join David ?

electrostatics is a small subset of electromagnetics, and with good cause.
its application is limited to static electric fields only. no current, no radiation, just static electric fields. so don't try to sell an antenna based on electrostatics or you will be lumped in with the e/h guys. coupling between elements of an antenna is a given, you can't have a conductor in an electromagnetic field without it coupling somehow to the field and re-radiating. to try to convince anyone otherwise is to ignore 100+ years of electromagnetic research. also, if you are basing this on new principles you can't expect eznec or ao or any of the existing finite element programs to do anything reasonable for it, they will all fall apart like the example you posted and give unobtainable models because they use classical electromagnetics to do all their calculations. as far as patents... i don't trust them any further than i can throw them, you can patent anything unless it says 'free energy' or 'perpetual motion' in it. heck there are even patents for faster than light antennas. if you can't explain the principles well enough to pass a peer review for something like the ieee a&p proceedings the science isn't right.

David it is not just limited to electrostatics. What Gauss wrote is accepted for what it is a mathematical deduction or law. That mathematical statement has universal use as with George Greens work who did not have one iota of engineering tuition. All I have added to gausses law is the dimension of time which I suspect that a mathematician can connect it to Amperes law or even Kirchoff As far as current is concerned a brief moment of time where a time varying field is applied to an element immediately the electric particles posses directive abilities where the vector value is zero. I may be wrong here but that is called a conservative field with a big but... the inside of the arbitary curve must be in a state of equilibrium where the sign on the particals must be alike and change in unison. This can be done by making the elerments resonant which mine are tho not of the same length. When the time varying field is applied to the cluster we break the equilibrium with an element that does not change in unison with the other elements thus weakening the arbitary border at that point./ When the energy of the internal field breaches the arbitary border it will do it in the vicinity of the added detuned element. It is only when the border is breached does one start generating the near field which is contrary to the yagi. Now with respect to coupling. in mathematics you try to remove some of the variables to make a solution easier, in this cas we removed the variable of coupling by using elements with the same "Q' I am not saying that I get radiation without current or coupling I am saying that I have reduced the design to just ohms law via mathematical aproaches, nothing more. coupling between elements of an antenna is a given, you can't have a conductor in an electromagnetic field without it coupling somehow to the field and re-radiating. to try to convince anyone otherwise is to ignore 100+ years of electromagnetic research. I accept coupling but not generation of a radiating field at the same time. Gausses law revolves around a closed arbitary border where the radiating field does not generate until the border is breached. This is why a detuned element is added to the cluster to weaken the border. also, if you are basing this on new principles you can't expect eznec or ao or any of the existing finite element programs to do anything reasonable for it, they will all fall apart like the example you posted and give unobtainable models because they use classical electromagnetics to do all their calculations. No they are not new principles they have existed for a long time Over the years mathematicians have connected many laws of different disciplines purly by mathematical terms, supposition or just going the extra mile with somebody elses work and George Green is a prime example of mathematical genious where his work was connected more than 100 years later to complexc circuitry and other things. as far as patents... i don't trust them any further than i can throw them, you can patent anything unless it says 'free energy' or 'perpetual motion' in it. heck there are even patents for faster than light antennas. if you can't explain the principles well enough to pass a peer review for something like the ieee a&p proceedings the science isn't right. Exactly. So I am asking for input from those experienced in the state of the art or a different perspectivebut there doesn't appear to be any out there to add their penny worth. I really believe Dave that the idea of adding curl to a electriostatic charge is what you are resisting and some day you will have to look at that afresh or at least poke academic holes in the aproach I am taking or a different perspective for me to mull over, a mathematical aproach requires not amateurs but those experienced in the art such as yourself. At least you gave it a shot Dave for which I thank you. I can give you another arbitary array where the elements are not as close to each other if you wish or the same array where the elements are rotated into a star fashion for vertical radiation to remove this close coupling which seems to be alarming you. I only supplied such an arbitary placed array to catch the imagination of those who are really inquisitive, nothing more Will another person knoweledgable in the field join in with us other than an amateur who knoweledge only extends to the ARRL examinations, anyone ? Surely since this is an antenna group somebody must have studied these things in college even tho it may have been a long time ago. Regards Art "art" wrote in message ups.com... David listen to me.

David this is just conjecture on your part. I respect your knoweledge but I am looking for academic proof. Your comments may well be valid in general terms but I have given a specific case plus some of my findings. Prove to me the error of my ways please Now I need the help from anybody with a engineering degree which wipes out Richard since his only intent is to ridicule, or deceive anyway, to confirm the following For a Gaussian field the energy radiated by the array as a whole ( feed element 1 ) must equal the sum of the energy supplied from each individual element. this is true for any array. O.K. and I gave you all the impedances that you would need to prove or disprove what I have said. I would be interested in what a academic would say regarding a proof measure based on the figures I've given which I believe is all that is needed Questions. 1. Am I correct in saying this? 2. Does the above array rank in any way as a Gaussian array.? define 'gaussian array' as it applies to antennas that you are describing. that type of array is not defined in my copies of Jackson's or Ramo-Whinner-VanDuzer's books, nor does my IEEE antenna design handbook mention that term. there are references to 'gaussian beams' with respect to the shape of the fields from feed horns for microwave dishes and other quasi-optical systems. Some searching of the web also seems to refer to gaussian arrays, but those all seem to be related to current or power distribution on elements of an adaptive array. Yes, these deal with other works of Gauss as he was primarily a mathematicial and his work is all the vogue now in the communications world with respect to channels. No you will not find it in books possibly because of the popularity of the Yagi were all that is known about antennas was known. I am absolutely positive that in time this will be picked up and put in the books because I am making it known and I gave several paragraphs that showed the trail of deductions using the word of the masters and nobody found fault that they could justify academically. Richard is known to lead people astray and he is doing it again. He, Richard has no engineering degree, he may have one on geography since he was in the navy and if you know what hemesphere the Panama canal is, and you get two shots at it you can get a degree in the mail. When I gave you the impedances it is the root of determining the energy supplied by a radiating element where Z1 Z2 etc is all you need Again I agree that this is not stated in the books but surely you don't believe all is in the books at the present time ? Electricity is not immune to new discovery. I welcome your comments but really I am looking for academic proof where Richard has muddled things up so much I am beginning to question myself even tho no facts only words have been offered unfortunately it is not possible to prove a negative. and you have not proved your case. I have pointed out the well known failure of finite element modeling that most of us with engineering degrees do understand and avoid. you have simply been misled by software that you don't understand completely. And no, I don't think everything is in books already, but I don't believe that someone playing around with software they don't understand is going to discover a new principle that hasn't been studied elsewhere. So, again I ask, please define 'Gaussian array', give web references that explain it if you can't, surely something that is on the cutting edge of technology will have many web sites trying to promote it, or sell antennas based on this design. |

But, now I am appealing to the academics or qualified engineers. (I once was an engineer but time has messed the mind in some areas}to help me out so I can finalise things but above all I want academic facts and not drivel that I get from those who follow Richard. Hi Art, You've repeated my name more times than Gauss. That sure gives it a lift. ;-) Is there any other academics out there that can help me out as well as clarifying what I say for better understanding. The clarification I offered was: Throw away 4 of the 5 wires and you improve both the gain and the match. If you dismiss this as drivel (a perverse contempt in this forum dedicated to gain and matching) then there is no clarification to be gained. As Dave pointed out, submit to a judged journal and show us the citation when it publishes. 73's Richard Clark, KB7QHC |

I know his use of the word 'possible' does not endorse anything but he didn't rule it out In addition page 70 refers in depth with respect to Gauss's law where he supplies a drawing of a partial surface of a volume ( arbitary surrounding surface is the statement ) where the charge is a projection on the surface without reference to what it is projected from. In my case it is a projection from a cluster of elements) definitions and concepts, without any furtherexperimental information He also goes on to state Gauss law in his own words and then goes on to say It has been derived from Coulombs force by the introduction of new definitions and concepts I am just adding to the concept by adding a third dimension which when looking at the drawing given reflects the original Gaussian thinking tho current thinking uses a two dimension section in describing electrostatics.I suppose a good proof would be to compare Pointings vector formulae with what I have put forward but perhaps that is too presumtious of me. All in all the array represents a band pass filter where effort is made for constant gain across a band of frequencies which is a different requirement from the Yagi where amateurs are only interested in gain without due referance to constancy across the frequency span or with regard to the corresponding beam width Any way the above should provide some food for thought Bed time calls Best regards Art Unwin nor does my IEEE antenna design handbook mention that term. there are references to 'gaussian beams' with respect to the shape of the fields from feed horns for microwave dishes and other quasi-optical systems. Some searching of the web also seems to refer to gaussian arrays, but those all seem to be related to current or power distribution on elements of an adaptive array. Frankly, one or more of you is an academic so I really am pointing at you for direction so I can be sure that my program has not somehow become corrupted I am sharing this with you so can you share your input with me? If you prefer to communicate by E mail with me that is fine since we know that the lips of some will spew Art |

All in all the array represents a band pass filter where effort is made for constant gain across a band of frequencies Hi Art, D.E. Isbell did this 46 years ago. which is a different requirement from the Yagi It has been used for TV antennas for lo those same 46 years and to any casual view looks like a Yagi. where amateurs are only interested in gain without due referance to constancy across the frequency span or with regard to the corresponding beam width Isbell got that too. It was, afterall, everyone's goal and he got: 1. More gain; 2. Better match; 3. More bandwidth; than 5 un-optimized wires hanging in the air. Isbell understood Gaus, Maxwell, McGuffey, and the rest and never appealed to bundles to explain his design (which really bore no more relation to his antenna than explaining why a car works in terms of how zippo lighters create a flame). D.E. Isbell's antenna is included free as an example with every copy of EZNEC. It contains 5 wires and exhibits: 1. 10% BW 2. 10 dBi gain 3. a serviceable match Isbell wrote the design up, submitted it to his peers, a jury passed on his work, it was published, it was patented (3210767) and it has stood the test of time. Isbell also explained how to achieve different: 1. Gains; 2. Matches; 3. Bandwidths; in terms that others could actually build working models. In regard to this last, I am sure amateur publications offer simple formula to achieve these goals too. However, if all one has to read is a book about fields, Isbell's invention may come as a surprise. Ramo and the boys don't really talk all that much about "antennas," so citing them as authorities on the subject makes as much sense as crediting Jane Goodall for the Theory of Evolution. 73's Richard Clark, KB7QHC |
