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. "art" wrote in message ups.com... 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 ? Regards Art Dave wrote: "art" wrote in message ups.com... Dave wrote: "art" wrote in message ups.com... 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 as i pointed out before, and this verifies, you have found one of the limitations of finite element methods for modeling antennas. very close spacings between long elements causes un-realizable results. the extremely low real components of the impedance and high reactive values are symptoms of this. 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. |
