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
Best regards

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
