Wow! I'd really like to see this vortex, sorry these vortices, that you
have produced.

Is the rotation right or left handed?

This is REALLY COOL!

Please post the file and which optimizer software that you are using.

Thanks!

The presence of these vortices are used to determine imperfections in
materials during manufacturing processes. Removing the presence of
such is the primary reason for laminations instead of solids in the
manufacture of transformers.I am surprised that you are not familiar
with the concept of skin depth when at the same time you consider
yourself as an expert with respect to antennas. The antenna program I
use is
AO Pro purely because it has an optimizer to ensure Maxwell's
equations are adhered to as well as accountability for all vectors
involved. Planar devices are quite efficient such as the Yagi but
planar devices are not in equilibrium which is a requirement of
Maxwell's equations! I imagine that with any program you could fiddle
with a dipole
construction such that it was resonant at a very low impedance to
obtain a progression for radiation
pattern /volume versus impedance if it does not posses optimization
abilities. The free EZNEC program probably will be good enough.
As far as vortices are concerned the same two vectors used with
antennas are also evident with the Earth's weather system. For
instance, a tornado
or a whirlpool presents a vortice by virtue of the intersection of two
vectors involved. Remove one intersecting vector and the vortice
disappears. This is an example of what Einstein saw with respect to
his leanings on the unified theory.

Oh that's right, I forgot. You use my god child. I asked Brian to do
that program for 2 or 3 years before he finally did. I was the alpha
tester on it and other of his programs.

You do know that's just MiniNEC, right? With all the problems MiniNEC
has included for your computing pleasure.

It's off frequency - low. And it gets worse as the wire diameter
INCREASES. Which is what you are doing in your example.

It also doesn't like bent wires, as in things that don't meet at 180
degrees. It breaks down completely at less than 28 degrees.

It doesn't like adjacent segments that are in a ratio greater than 2 to 1.

And it doesn't like adjacent wires that are closer than .23 of a segment
length.

Given some of the things you have posted that you have modeled, I'd
guess that you break a minimum of 1, normally 2, and sometimes 3 of the
above conditions.

No wonder your stuff acts abnormal.

And you are using this tool to attempt to prove your twisted theories
about Maxwell's equations? That's like using a chain saw to do brain
surgery.
