create_bmp_for_symmetrical_sGeneraleComcreate_bmp_for_symmetrical_stripline(1)

NAME
       create_bmp_for_symmetrical_stripline  -	bitmap generator for thin con-
       ductor 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	 docu-
       mentation  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 analyti-
       cal answer, when	the inner is infinitely	thin and the width W is	infin-
       itely wide. This	theoretical impedance is also calculated by  the  cre-
       ate_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  con-
       ductor.	 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 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 create_bmp_for_symmetrical_stripline are	24-bit
       bit   colour   bitmaps,	 as  are  required  by	atlc.  Currently  cre-
       ate_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 dis-
       agree wildly.
