sym_strip(1)

NAME
sym_strip - bitmap generator for thin conductor betwen two infinite groundplanes (part of atlc)

SYNOPSIS
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, centrally 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 conductor 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 surrounded 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 bitmaps, as are required by atlc. Currenly sym_strip only produces bitmaps with white (vacuum) dielectrics.

OPTIONS
There are no options for sym_strip.
