Enersearch has experimented geometrically
with some interference patterns using a 3D CAD software.
This software can be downloaded
as a free demo at www.formZ.com
Above is a tranparent rendering
of geometric objects which can represent radial waves fronts from
just two points. In this graphic, both sources start with blue,
circular waves of the same size and alternate with red, blue,
red, etc... The resulting pattern is developed to the point where
the outermost wave fronts reach the opposite source point.
Next, above, are 30 source points
which alternate. Again the rendering is transparent.
Next, above, are three source points
close up. The center source is opposite to the sources at either
end, right and left. The cancelation points where opposite wave
front polarities meet was colored green. The question is: could
parasitic elements be modeled advantageously in this way and suspended
in a potting material?
Above, the green cross sections
have been magnified and isolated. Below, a 3D version has been
mocked up by rotating the cross sections along the vertical axis.
Since the elements are planar surface objects, those which are
near center effectively appear invisible. More accurately, solid
geometry can be employed with booleans to build truer modeling
experiments. Enersearch would like to cooperate with others in
need of the the 3D geometry data for development of antenna models.

Searching Synergy ........ Free Exchange of Ideas
Enersearch was incorporated in 1980 but never materialized financially. A synergy of concepts were developed and are reflected in the pages of this series. The synergy continues as a single handed effort of Bo Atkinson, in Maine, USA.
