To keep it simple, Gauss' Law is precisely one of the four standard

As for electromechanics, who knows?

Gene, forgive me if I am incorrect but I am going to assume you have
an engineering degree and are fully conversant with the work of the
masters. I f I am not correct then we can stop at this point Otherwise
I fully recommend that you check out the web foe a book on fields and
waves or something like that by a professor at Rutgers University. In
chapter 21 he delves very deeply into an array consisting of four
elements all of which are resonant.
Ofcourse he doesn't mention anything of mine but you will notice that
the array he chose is actually what I refer to as a Gaussian array
since it meets all the requirements that I have expoused on my page.
He doesn't use computor programs but basic mathematics to provide all
the desirables plus a radiation field. This array is really a
derivitation of one designed some 50 years ago and is the only one I
know that exists in literature. If you study this chapter and relate
it to what I am expousing then possible you will see things with fresh
eyes. But again if you are not fully educated in this field save your
self from the bother. I personaly have a program that if you isert any
fugure and tell it to obtain maximim gain I assure you it will not
produce a yagi but a gaussian array........ and I am thrilled with
that.
Nuff said

Art,

You seem to have misunderstood my point.

AAALLLLLL antennas, regardless of structure, material, efficiency,
resonance, location, or phase of the moon are Gaussian. Gauss' Law is an
integral part of classical electromagnetics. Nothing can escape.

No, I do not have an engineering degree, but I do have several degrees
in physics. Unfortunately, I am significantly dumber than a rock, so I
have no more to offer in this thread.

Watch out Gene, I stated that Statics was a subset of electromagnetics
and I caught hell from everybody. Seems like things are infectional
around here.The book that I proferred would really be to much for a
lot of people no matter how much they over estimate their abilities
especially when they try to debate reasons why the writer is incorrect!
When I asked for academic help regarding research I got an Email from
a guy at the space antenna agency who referred me to chapter 1 and 21.
I never dreamt that I would find an actual array with all elements
resonant being discussed

no need to be surprised at having an antenna with elements that are
all phased. I doubt if ther is anyone on the news group that doesnt
know that a Yagi Uda antenna doesnt represent some kind of comprimise
to an antenna with all of the elements feed. No one has ever said
otherwise although you have claimed they have.
The problem with having all the elements feed is that it is
impractical to control power distribution and phasing when changing
frequencies. The Yagi Uda overcomes this problem at a slight cost in
gain. Your idea of an antenna with multiple fed resonant elements is a
giant step backwards to a day when high gain steerable antennas were
impractical most of the hams who didnt have the money or the real
estate for huge arrays

Antenna with multiple resonant element all being fed is very common in
RADAR and space communication, you can achive very high gains in this
manner just as you have stated. It is also very expensive, has narrow
bandwidth and is a mechanical nightmare. NASA, AM BCB, commercial
shortwave stations and various other agencies and private companies
sometimes have a need for this type of antenna and they they have the
money to build them, few hams do. The Yagi Uda antenna just fills a
practical niche in antenna requirements. No ham I know of ever thought
the Yagi antenna was the end-all of antennas as you have claimed.
While it may not have the highest gain it certainly is the most
practical antenna for a lot of us.

Jimmie, I have to congratulate you on your posting
and your width of knoweledge.
I for one was unaware that what I call a gaussian
array was in publication and I would really
appreciate a pointer where I could obtain more
information on this. I have a multitude of books with
respect to fields and waves plus antennas but with
the advance of new technologies it is difficult for
my bill fold to keep pace.
As a further favor could you repeat the program test
I proffered in my latest posting? I am asking since
I know that your responses would be very
worthwhile in reading since you appear to be a
scholar that searches for truth
and you would not be afraid to publisize your
program used and result for the benefit
of all.
Thank you for your input and hopefully you
will continue sharing
Best regards
