yep, thats it. a time varying field makes charges move, so they are no
longer static... that is how coupling works and its a fact of life. maybe
you should try sci.physics.electromag or alt.sci.physics.new-theories, they
are more open to theoretical questions.

So David we come to the end of the debate where you and probably others
who are members of this newsgroup state you can't impose a time varying
field on a array of static charges which is contrary to what I say.
Thus a standard of education has been set for the many engineers in
this group and where I am just a group of one.
So be it
Regards
Art

we totally disagree, you have a hang up on applying a time varying
field to a electric charge. There is absolute no reason that you
can
take
a stand on that.

of course i can, rf is a time varying phenomenon by definition. you
can't
communicate via static fields, by definition, so they are of no use in
this
discussion.

David, it stops being a static field alone if a time varying fiels is
applied


You say that you worked in space communication well
ask for a second opinion from one of your former associates or even
ckeck with your Alma Mata before you dig a hole that is to deep to
get
out of.Remember that as we get older we all have senior moments and
I
may well be having more than you so hang in there!

no, i don't work in space communications other than occasionally
listening
to ariss.


Regarding the need for a new program that just can't be true, NEC is
based on known mathematical laws period. When programs first came
out I
struggled with that but I then realised that NEC is NOT based on
empirical data so what you are saying is just not correct.
I urge you to rethink that one out again.



of course it's true. nec and other existing antenna modelling
software
is
all based on maxwell's equations so by definition it assumes time
varying
fields and coupling between all the elements of the antenna. if you
are
trying to do something and ignore that coupling then none of the
existing
programs will work for you.

David,
I never said there is no coupling, in mathematics there are ways of
removing avariable by the use of simultaneous equations. If you can't
get around it then ofcourse you have to go the labourious route for
full determination and that is compicated Going the Gaussian rout
removes all that laborious mathematical work. Look at any mathematical
sample of such an array and it all comes down to ZI of the elements
involved, nothing more is needed
and coupling is part of the journey but not of the solution and the
solution by my method goes straight to the the solution by using the
same laws that have been in existant for years.

then you have nothing new and you should be made aware of the limitations
of
the software you are using so that you don't get misled any further.
unfortunately i don't believe that you have really found anything new,
you
are probably just ignoring important parts of the solution because you
think
you can incorrectly apply a static case simplification to a time varying
one... sorry, that doesn't work. you may find some examples in certain
cases where it looks like it works, but in general it won't.
