These models used 3D software to determine interference patterns of waves represented by color coding rings. (This software can be downloaded
as a free demo at www.formZ.com ).
Above is a transparent 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. I would like to cooperate with others in
need of the the 3D geometry data for development of antenna models.
