NAME

       create_bmp_for_symmetrical_stripline  -  bitmap  generator  for thin conductor between two
       infinite groundplanes (part of atlc)

SYNOPSIS

       create_bmp_for_symmetrical_stripline [-v] W H w bitmapfile

WARNING

       This man page is not a complete set of documentation - the complexity of the atlc  project
       makes  man  pages not an ideal way to document it, although out of completeness, man pages
       are produced.  The best documentation that  was  current  at  the  time  the  version  was
       produced should be found on your hard drive, usually at
       /usr/local/share/atlc/docs/html-docs/index.html
       although  it  might be elsewhere if your system administrator chose to install the package
       elsewhere.  Sometimes,  errors  are  corrected  in  the  documentation   and   placed   at
       http://atlc.sourceforge.net/  before  a  new  release of atlc is released.  Please, if you
       notice a problem with the documentation - even spelling errors and typos,  please  let  me
       know.

DESCRIPTION

       create_bmp_for_symmetrical_stripline  is  a  pre-processor for atlc, the finite difference
       program  that  is  used  to  calculate  the  properties  of  a  two-conductor   electrical
       transmission      line      of      arbitrary      cross      section.     The     program
       create_bmp_for_symmetrical_stripline is used as a fast way of generating bitmaps (there is
       no  need  to  use a graphics program), 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 create_bmp_for_symmetrical_stripline.
       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  create_bmp_for_symmetrical_stripline  are  24-bit  bit  colour
       bitmaps,  as  are  required  by  atlc. Currently create_bmp_for_symmetrical_stripline only
       produces bitmaps with white (vacuum) dielectrics.

OPTIONS

       -v
       Print the theoeretical impedance Zo. This only works if the width W is sufficiently  wide,
       otherwise atlc and the value printed here would disagree wildly.
