sym_strip W H w bitmapfile
WARNING
This man page is not a complete set of documentation. See
the html files for more complete information. So far, I've
not managed to install the html files into /usr/local, so
you will have to look into the atlc-X.Y.Z/docs/html-docs
directory for them.
DESCRIPTION
sym_strip is a pre-processor for atlc, the finite difference
programme that is used to calculate the properties of a
two-conductor electrical transmission line of arbitrary
cross section. The programme sym_strip is used as a fast way
of generating bitmaps (there is no need to use a graphics
programme), for a 1 pixel thick conductor of width w, cen-
trally located inside a pair of groundplanes of width W and
separation H. This has an exact analytical answer, when the
inner is infinitely thin and the width W is infinitely wide.
This theoretical impedance is also calculated by the
sym_strip. It is therefore used as a test of atlc.

The parameters 'W' and 'H' and the inner dimensions of the
outer conductor. The outer dimensions of the inner conduc-
tor are 'w' and 'c'. The inner conductor is assumed to rest
on a dielectric (Er2) which is 'd' wide and outer conductor
an the inner conductor is offset 'b' from the left hand
sidewall of the outer conductor. The whole region is sur-
rounded by a dielectric of relative permittivity 'Er1'. The
dielectrics 'Er1' and then 'Er1' and 'Er2' will both be 1.0
The bitmaps produced by sym_strip are 24-bit bit colour bit-
maps, as are required by atlc. Currenly sym_strip only pro-
duces bitmaps with white (vacuum) dielectrics.
